Description

Technical Field

[0001] This invention relates to the field of breast milk dispensing technology, and more specifically to an automatic dispensing device for mixing breast milk that can measure its volume. Background Technology

[0002] Breast milk is the most natural, safest, and most complete food for infants. It contains all the nutrients and antibodies needed for infant growth. The abundant calcium and phosphorus help babies grow tall and strong (promoting bone development), while immunoglobulins effectively prevent and protect infants from infections and chronic diseases. Bifidobacteria and oligosaccharides inhibit the growth of intestinal bacteria and aid digestion. Currently, in neonatal wards where mothers and infants are separated, collected breast milk needs to be fed to the infants. This involves the collection, transportation, storage, packaging, and feeding of breast milk. Ensuring that breast milk is properly distributed after it arrives at the hospital, without waste or contamination, is a crucial link in the breast milk closed-loop system.

[0003] Our hospital's breast milk bank stores donated breast milk. Before using this milk, it needs to be sterilized and tested. Only after passing the test can it be used to feed newborns. The breast milk in the bank is stored in milk storage bags, and the milk stored in each bag comes from donations from different mothers. If we were to sample and test the milk in each storage bag individually, the operation would be cumbersome and the workload would be very large. Therefore, the current operation procedure is as follows: First, the milk from all the storage bags of the same batch is poured into a mixing container and mixed. Then, the milk is dispensed into multiple dispensing bottles through the mixing container to ensure that the milk in each dispensing bottle contains all the samples. Then, the dispensing bottles are placed in a sterilizer for water bath sterilization. Finally, one or more dispensing bottles are randomly selected for microbial testing. If the test results are qualified, the milk can be allocated to the neonatal ward.

[0004] However, the above operation process still has the following technical problems: First, the milk from multiple milk storage bags is poured into a mixing container and mixed, and then the milk is poured into each individual bottle through the mixing container. These are all manual operations, which are cumbersome, time-consuming and labor-intensive. In addition, the milk in the larger mixing container is prone to leakage when being poured into the smaller individual bottles, which leads to milk waste. Summary of the Invention

[0005] The present invention aims to provide an automatic dispensing device for mixing milk that can measure milk volume, so as to solve the technical problems of the cumbersome, time-consuming and labor-intensive mixing and dispensing process in the existing process.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An automated dispensing device for mixing milk, capable of metering, includes a feeding device, a suction device, a mixing container, and a dispensing mechanism. The feeding device includes a conveyor belt for transporting milk storage bags. The suction device, mounted on a bracket at the end of the conveyor belt, suctions milk from the storage bags and delivers it to the mixing container. A discharge pipe with a control valve is located at the bottom of the mixing container. The dispensing mechanism, located below the mixing container, dispenses the milk from the container. The dispensing mechanism includes a conveyor chain and a guide plate positioned above and parallel to the conveyor chain. The conveyor plate is provided with a positioning groove for the discharge pipe to pass through and a guide groove along its length. The positioning groove and the guide groove are connected. The guide groove is divided into an inclined section and a horizontal section along the conveying direction of the conveyor chain and with the positioning groove as the boundary. The lower end of the inclined section is close to the positioning groove. The conveyor chain is provided with a mounting base that can float up and down. The top of the mounting base is provided with an elastic block. The elastic block is provided with an elastic groove for fixing the dispensing bottle. The bottle mouth of the dispensing bottle is located in the guide groove. When the dispensing bottle is conveyed forward to the positioning groove, it is aligned with the discharge pipe, and the bottle mouth of the dispensing bottle is larger than the opening of the discharge pipe.

[0008] Beneficial effects:

[0009] 1. By setting up a feeding device to transport milk storage bags, a suction device to draw milk from the milk storage bags into a mixing container, all the milk is mixed evenly in the mixing container, and a discharging mechanism to dispense the milk in the mixing container, the milk is automatically mixed and dispensed, reducing the workload of operators and improving the efficiency of milk mixing and dispensing.

[0010] 2. A guide plate is installed above the conveyor chain, and a guide groove is provided on the guide plate to guide and limit the dispensing bottles. When the dispensing bottles are conveyed forward with the conveyor chain, the inclined section of the guide groove will gradually squeeze the dispensing bottles downward. Since the dispensing bottles are placed on the mounting base that can float up and down, the mounting base is squeezed downward. When the dispensing bottles continue to be conveyed forward to the positioning groove, they lose the squeezing force of the inclined section. At this time, the mounting base floats upward and pushes the dispensing bottles upward. Since the bottle opening is larger than the outlet pipe opening, the outlet pipe opening is inserted into the bottle opening at the moment the dispensing bottles move upward, thereby achieving positioning and alignment during dispensing. This solves the problem of easy leakage when manually pouring milk from a larger mixing container into a smaller dispensing bottle.

[0011] 3. An elastic block is installed on the mounting base, and an elastic groove is opened on the elastic block. This not only fixes the dispensing bottle in the elastic groove to prevent it from tipping over during transportation, but also allows the dispensing bottle to have a certain amount of room to move. For example, when the dispensing bottle is not completely aligned with the discharge port, because the elastic block is made of flexible material, the dispensing bottle can self-adjust by moving when it encounters an obstacle. This is more adjustable than rigid limiting parts.

[0012] Preferably, as an improvement, the mounting base includes a base and a floating plate. The base is disposed on the conveyor chain, and the top of the base is recessed downward to form a mounting cavity. The floating plate is disposed in the mounting cavity by a spring, and the side wall of the floating plate is slidably connected to the cavity wall of the mounting cavity. An elastic block is disposed on the floating plate.

[0013] Beneficial effects: The floating mechanism utilizes a spring to achieve vertical movement. When the inclined section of the guide groove presses down on the dispensing bottle, the spring contracts under pressure. When the bottle is in the positioning groove, it loses the pressure from the inclined section, causing the spring to reset. The floating plate then moves upward, lifting the bottle and allowing the outlet pipe to insert into the bottle opening. As the amount of milk in the bottle increases, the spring is compressed again under gravity, causing the floating plate to move downward and disengage the bottle opening from the outlet pipe and positioning groove, facilitating the continued forward transport of the bottle containing milk. The side wall of the floating plate is slidably connected to the cavity wall of the mounting chamber, which limits the movement of the floating plate and prevents milk from spilling out of the bottle due to deflection.

[0014] Preferably, as an improvement, the discharge pipe is provided with a conical limiting cylinder in the circumferential direction of the positioning groove, and the bottom edge of the limiting cylinder is aligned with the lowest end of the inclined section of the guide groove.

[0015] Beneficial effects: The conical inner wall of the limiting cylinder can limit and guide the bottle opening of the dispensing bottle, improve the accuracy of the insertion of the discharge pipe into the bottle opening, and further reduce the risk of milk leakage during dispensing.

[0016] Preferably, as an improvement, the suction device includes a negative pressure cylinder and a needle holder that can move up and down. The negative pressure cylinder is fixedly mounted on a support, and the needle holder is equipped with a needle for puncturing the milk storage bag. The negative pressure cylinder is equipped with an inlet hose and an outlet hose. The inlet hose is connected to the needle, and the outlet hose is connected to a mixing container. The inlet hose is equipped with an inlet check valve, and the outlet hose is equipped with an outlet check valve. The length of the inlet hose is greater than the maximum distance between the negative pressure cylinder and the needle holder, so that the inlet hose can move up and down with the needle holder.

[0017] Beneficial effects: The needle is designed to puncture the milk storage bag. Under negative pressure, the milk in the storage bag enters the negative pressure cylinder through the needle and the feed hose. Since both the feed hose and the discharge hose are equipped with one-way valves, the milk can only enter the mixing container along the discharge hose after entering the negative pressure cylinder. The length of the feed hose is greater than the maximum distance between the negative pressure cylinder and the needle holder, allowing the feed hose to have a margin of movement. It can move along with the needle holder when it moves up and down.

[0018] Preferably, as an improvement, the support is also provided with a drive assembly, the power output end of which is connected to the needle holder, and the needle holder is driven to move up and down through the drive assembly; a piston and a push rod are provided inside the negative pressure cylinder, the bottom of the push rod is connected to the piston, the top of the push rod protrudes through the top of the negative pressure cylinder and is slidably sealed to the negative pressure cylinder, and a cylinder is provided on the support, the piston rod of the cylinder is connected to the push rod.

[0019] Beneficial effects: When the milk storage bag is below the syringe holder, the drive assembly drives the syringe holder to move down, thereby puncturing the milk storage bag with the needle. When all the milk in the milk storage bag is drawn into the negative pressure cylinder, the drive assembly drives the syringe holder to move up. After the next milk storage bag is delivered to the bottom of the syringe holder, the above process is repeated. The piston is pulled by the push rod to draw the milk in the milk storage bag into the negative pressure cylinder, and then the piston is pushed down to push the milk in the negative pressure cylinder into the mixing container.

[0020] Preferably, as an improvement, the bottom of the needle holder is also provided with a negative pressure suction cup, through which the needle tip passes; a negative pressure tube is connected to the negative pressure suction cup, and a solenoid valve for controlling the gas flow is provided on the negative pressure tube.

[0021] Beneficial effects: The negative pressure suction cup can adhere to the upper surface of the milk storage bag. When the needle punctures the milk storage bag and draws out the milk, the negative pressure suction cup adheres to the upper surface of the milk storage bag, which makes the milk storage bag more upright. This makes it easier to draw out the milk and reduces the problem of milk leakage from the puncture point.

[0022] Preferably, as an improvement, the mixing container is provided with scale lines and is made of transparent material, and the control valve on the discharge pipe is connected to a controller; the drive assembly, cylinder and solenoid valve are all electrically connected to the controller.

[0023] Beneficial effects: The setting of graduated lines and transparent mixing container makes it easy to see the amount of milk in the mixing container. In addition, the controller can set the opening time of the control valve on the discharge pipe, thereby controlling the amount of milk entering the dispensing bottles, so that each dispensing bottle is filled with an equal amount of milk, which is convenient for measurement and statistics.

[0024] Preferably, as an improvement, the bracket is also equipped with a sensor for detecting the milk storage bag. The sensor is electrically connected to the controller. When the sensor detects that the milk storage bag is located below the needle holder, it transmits a signal to the controller, which then controls the drive assembly, solenoid valve and cylinder to start sequentially.

[0025] Beneficial effects: By setting up sensors to detect signals and transmitting them to the controller, fully automatic feeding, suction, mixing and dispensing can be achieved, with a high degree of intelligence.

[0026] Preferably, as an improvement, the end of the guide plate is also equipped with a sealing machine or an automatic capping machine.

[0027] Beneficial effects: A sealing machine can be used to seal the mouth of the dispensing bottles, or an automatic capping machine can be used to tighten the caps. Attached Figure Description

[0035] Example 1

[0036] like Figure 1-4As shown, an automatic dispensing device for mixing milk can be metered. This device can be protected by a protective cover or placed separately in a room (e.g., a cleanroom) (not shown in the figure) to reduce the risk of contamination. Specifically, the device includes a feeding device 1, a suction device 2, a mixing container 3, and a discharge mechanism 4. The feeding device 1 includes a conveyor belt 11 for transporting milk storage bags 12. In this embodiment, to facilitate the positioning of the milk storage bags 12, several limiting frames 111 can be provided on the conveyor belt 11, and the milk storage bags 12 are placed within the limiting frames 111. The suction device 2 is located at the end of the conveyor belt 11 via a bracket 20, and is used to suction the milk from the milk storage bags 12 and deliver it to the mixing container 3. The mixing container 3 has a discharge pipe 31 at its bottom, and a control valve 32 is provided on the discharge pipe 31. In this embodiment, the mixing container 3 is made of a transparent material, such as a transparent glass mixing container. Graduation lines are provided on the outer wall of the mixing container 3 for easy viewing of the amount of milk inside.

[0037] like Figure 1 As shown, the suction device 2 includes a negative pressure cylinder 22 and a needle holder 21 that can move up and down. The negative pressure cylinder 22 is fixedly mounted on the support 20. A piston 24 and a push rod 25 are installed inside the negative pressure cylinder 22. The bottom of the push rod 25 is connected to the piston 24, and the top of the push rod 25 extends out of the top of the negative pressure cylinder 22 and is slidably sealed to the negative pressure cylinder 22. A cylinder 23 is fixedly mounted on the top of the support 20. The piston rod of the cylinder 23 is connected to the push rod 25. By extending and retracting the cylinder 23, the push rod 25 is pulled to generate negative pressure inside the negative pressure cylinder 22. The needle holder 21 is provided with a needle 211 for puncturing the milk storage bag 12. Specifically, the needle 211 can be glued and fixed to the needle holder 21, or a rubber block can be set on the needle holder 21, allowing the needle 211 to pass through the rubber block. The rubber block is then locked with a cable tie, thereby firmly installing the needle 211 on the needle holder 21. The bottom of the syringe holder 21 is also equipped with a negative pressure suction cup 212, through which the needle 211 passes. The negative pressure suction cup 212 is existing technology. Specifically, a negative pressure tube 2121 is connected to the negative pressure suction cup 212, and a solenoid valve for controlling the gas flow is installed on the negative pressure tube 2121. The negative pressure cylinder 22 is equipped with an inlet hose 221 and an outlet hose 222. The inlet hose 221 is connected to the needle 211, and the outlet hose 222 is connected to the mixing container 3. An inlet check valve is installed on the inlet hose 221, and an outlet check valve is installed on the outlet hose 222. The length of the inlet hose 221 is greater than the maximum distance between the negative pressure cylinder 22 and the syringe holder 21, so that the inlet hose 221 has a large margin and can move up and down with the syringe holder 21.

[0038] Specifically, the bracket 20 is provided with a drive assembly for driving the needle holder 21 to move up and down. The power output end of the drive assembly is connected to the needle holder 21. In this embodiment, the drive assembly adopts the existing electric push rod 213. Specifically, the output end of the electric push rod 213 is fixed with a connecting rod. The bottom of the connecting rod is connected to the needle holder 21. The bracket 20 is also provided with a limiting sleeve 214. The connecting rod and the limiting sleeve 214 are slidably connected. When the milk storage bag 12 is below the needle holder 21, the drive assembly drives the needle holder 21 to move downward, thereby puncturing the milk storage bag 12 through the needle 211. At this time, the negative pressure suction cup 212 adheres to the upper surface of the milk storage bag 12, so that the milk storage bag 12 can maintain a better upright state. This facilitates suction and reduces the leakage of milk from the puncture point. When all the milk in the milk storage bag 12 has been suctioned into the negative pressure cylinder 22, the drive assembly drives the needle holder 21 to move upward. After the next milk storage bag 12 is delivered to the needle holder 21, the above process is repeated. The milk in the negative pressure cylinder 22 is pushed downward by the cylinder 23 to the push rod 25, so that the milk enters the mixing container 3 through the discharge hose 222.

[0039] The feeding mechanism 4 is located below the mixing container 3 and is used to dispense the milk in the mixing container 3. The feeding mechanism 4 includes a conveyor chain 42 and a guide plate 41 arranged above the conveyor chain 42 and parallel to the conveyor chain 42. The guide plate 41 is provided with a positioning groove 412 through which the discharge pipe 31 passes and a guide groove 411 arranged along its length. The positioning groove 412 is connected to the guide groove 411. The guide groove 411 is divided into an inclined section and a horizontal section along the conveying direction of the conveyor chain 42 and with the positioning groove 412 as the boundary. The lower end of the inclined section is close to the positioning groove 412. The conveyor chain 42 is equipped with multiple floating mounting bases 5, which are evenly spaced and used to fix the bottom of the dispensing bottle 43. The bottle opening of the dispensing bottle 43 is located in the guide groove 411. When the dispensing bottle 43 is conveyed forward to the positioning groove 412, the conveyor chain 42 stops conveying. At this time, the dispensing bottle 43 is aligned with the discharge pipe 31, and the bottle opening of the dispensing bottle 43 is larger than the opening of the discharge pipe 31.

[0040] Specific examples Figure 2-3 As shown, the mounting base 5 includes a base 51 and a floating plate 52. The base 51 is fixed to the connecting ear plate 421 of the conveyor chain 42 by bolts. The top of the base 51 is recessed downward to form a mounting cavity 511. The floating plate 52 is disposed in the mounting cavity 511 by a spring 53, and the side wall of the floating plate 52 is slidably connected to the cavity wall of the mounting cavity 511. An elastic block 54 is also provided on the top of the floating plate 52. Specifically, the elastic block 54 is made of rubber and has a certain deformation capacity. The elastic block 54 is provided with an elastic groove 541 for fixing the dispensing bottle 43. Figure 3As shown, there are two elastic blocks 54 arranged symmetrically, and the elastic groove 541 is an arc-shaped groove. The two arc-shaped grooves form a placement area for the dispensing bottle 43. When the dispensing bottle 43 is conveyed forward, due to the inclined setting of the guide groove 411, the dispensing bottle 43 is squeezed downward by the inclined section of the guide groove 411. At this time, the spring 53 is compressed and contracted. When the dispensing bottle 43 is conveyed to the positioning groove 412, it loses the squeezing force of the inclined section. At this time, the compressed spring 53 returns to its original position, and the floating plate 52 moves upward, causing the dispensing bottle 43 to bounce upward, thereby allowing the nozzle of the discharge pipe 31 to be inserted into the bottle mouth. As the milk in the dispensing bottle 43 increases, the spring 53 is compressed again under the action of gravity, and the floating plate 52 moves downward, causing the bottle mouth of the dispensing bottle 43 to disengage from the discharge pipe 31 and the positioning groove 412, so that the dispensing bottle 43 containing milk can continue to be conveyed forward.

[0041] To achieve automated control, this embodiment also includes a controller (not shown in the figure). The controller can be a PLC controller. The electric push rod 213, cylinder 23, solenoid valve, and control valve 32 on the discharge pipe 31 are all electrically connected to the controller. The bracket 20 is also equipped with a sensor for detecting the milk storage bag 12. The sensor can be an infrared sensor, and the sensor is electrically connected to the controller. Specifically, a control method for an automatic dispensing device for milk mixing that can measure milk is as follows:

[0042] S1. Milk storage bag conveying: Place the milk storage bag 12 in the limit frame 111 on the conveyor belt 11. The conveyor belt will transport the milk storage bag 12 to the bottom of the needle holder 21. At this time, the sensor on the holder 20 will detect the milk storage bag 12 and send a signal to the controller. The controller will control the conveyor belt 11 to stop.

[0043] S2, Milk Suction: After the conveyor belt stops running, the controller controls the electric push rod 213 to extend, which in turn causes the needle holder 21 to move down until the needle 211 punctures the milk storage bag 12. At this time, the controller controls the piston rod of the cylinder 23 to retract, and the piston rod pulls the push rod 25 and the piston 24 located in the negative pressure cylinder 22, thereby sucking the milk into the negative pressure cylinder 22. During the suction process, the controller controls the solenoid valve on the negative pressure tube 2121 to open, and the negative pressure tube 2121 draws negative pressure, causing the negative pressure suction cup 212 to adhere to the upper surface of the milk storage bag 12, keeping the milk storage bag 12 in an upright state, which facilitates milk suction and reduces milk leakage from the puncture point. After the suction is completed, the electric push rod 213 retracts and drives the needle holder 21 to move up, waiting for the next milk storage bag 12 to be delivered to the bottom of the needle holder 21.

[0044] S3, Milk Mixing: When the electric push rod 213 retracts, it indicates that the milk in the milk storage bag 12 has been completely sucked out. At this time, the controller controls the piston rod of the cylinder 23 to extend. The piston rod pushes the push rod 25 and the piston 24 to move down in the negative pressure cylinder 22. Since the feed hose 221 is equipped with a feed one-way valve, the milk enters the mixing container 3 along the discharge hose 222. Whenever new milk enters the mixing container 3, it will stir the existing milk, thereby achieving automatic mixing.

[0045] S4. Pre-packaging detection: When the sensor set at the suction end does not detect the milk storage bag 12 within the set time range, it means that all the milk storage bags 12 in this batch have been suctioned, indicating that the milk can be packaged. At this time, the controller controls the conveyor chain 42 to start to transport the packaging bottles 43.

[0046] S5. Bottle conveying: Bottles 43 are placed sequentially in the elastic grooves 541. The conveyor chain 42 conveys the bottles 43 to the discharge pipe 31. During this process, the bottles 43 are subjected to pressure from the inclined section of the guide groove 411, which causes the floating plate 52 to move down to adapt to the guide groove 411 and achieve normal transmission. When the bottles 43 are conveyed to the positioning groove 412, the bottles 43 bounce upward and the discharge pipe 31 is inserted into the bottle mouth of the bottles 43. At this time, the controller controls the conveyor chain 42 to stop.

[0047] S6. Metering and Dispensing: When the discharge pipe 31 is inserted into the bottle opening of the dispensing bottle 43, the controller controls the control valve 32 on the discharge pipe 31 to open, and the milk in the mixing container 3 enters the dispensing bottle 43 through the discharge pipe 31. The controller sets the opening time of the control valve 32 to control the amount of milk entering the dispensing bottle 43, thereby ensuring that the amount of milk in each dispensing bottle 43 is basically consistent, which facilitates subsequent metering, statistics and distribution, thus realizing milk metering; when the milk in the dispensing bottle 43 reaches the set amount, the control valve 32 on the discharge pipe 31 closes, and the conveyor chain 42 starts to continue to transport the dispensing bottle 43 forward; since the dispensing bottle 43 is filled with milk, the spring 53 is compressed by gravity, at this time the bottle opening of the dispensing bottle 43 is lower than the opening of the discharge pipe 31. When the conveyor chain 42 starts, the dispensing bottle 43 continues to be transported forward; thus realizing the purpose of automatic milk dispensing.

[0048] Example 2

[0049] The difference between this embodiment and Embodiment 1 is that a sealing machine or an automatic capping machine is also provided at the end of the guide plate 41. The sealing machine can be used to seal the mouth of the dispensing bottle 43. For example, the sealing machine can be an existing milk tea sealing machine; or the cap can be tightened by an automatic capping machine. The sealing machine and the automatic capping machine in this embodiment both adopt existing technology, and will not be described in detail here.

[0050] Example 3

[0051] The difference between this embodiment and embodiment two is that the inclined section of the guide groove 411 is also equipped with a disinfection lamp, which can disinfect the bottle mouth of the dispensing bottle 43 located in the guide groove 411.

[0052] Example 4

[0053] The difference between this embodiment and embodiment three is that a stirring paddle is provided inside the mixing container 3, and a motor is provided on the top of the mixing container 3 to drive the stirring paddle to rotate. The stirring paddle can make the milk in the mixing container 3 more evenly mixed.

[0054] Example 5

[0055] The difference between this embodiment and Embodiment 1 is that, as Figure 5 As shown, a conical limiting cylinder 311 is provided around the positioning groove 412 in the circumferential direction of the discharge pipe 31, and the bottom edge of the limiting cylinder 311 is aligned with the lowest end of the inclined section of the guide groove 411. The inner wall of the conical limiting cylinder 311 can limit and guide the bottle mouth of the dispensing bottle 43, improve the accuracy of the pipe mouth of the discharge pipe 31 being inserted into the bottle mouth, and further reduce the risk of milk leakage during discharge.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the technical solutions of the present invention, and these should also be considered within the scope of protection of the present invention. These modifications and improvements will not affect the effectiveness of the implementation of the present invention or the practicality of the patent.
