Description

Technical Field

[0001] The utility model relates to a configuration mechanism and a high-precision fully automatic individualized medical formula food configuration machine. Background Art

[0002] With the current comprehensive attention paid to clinical nutrition work, medical formula foods are gradually accepted by the clinic. The workload of nutrition department in nutrition allocation has increased year by year, and the main mode of nutrition allocation work is still manual operation. According to the components, quality, concentration, temperature and dosage form of the doctor's prescription, different powder components are taken and weighed separately, and then put into containers (cups or bags) as required. Then, drinking water of different temperatures is prepared according to the requirements, and water is added according to the calibration liquid volume, mixed, and sealed before being sent to patients. This is not only time-consuming and labor-intensive, but also has high labor costs. The risk of food contamination caused by continuous long-term exposure and cross-operation is also high, and the error rate is large.

[0003] There are also weighing devices for dispensing (dosing) powders in the prior art, which manually or automatically add multiple materials to a weighing device in turn for weighing and then transfer them to a stirring device for mixing, and then batch-pack the load consisting of multiple bulk materials according to the pre-set charging value. This is suitable for industrial-grade mass production, but cannot meet the individualized configuration scenario of a single person and a single dose at a medical institution. In addition, sharing the same weighing and stirring device is prone to residual material contamination, and other concentration and temperature configuration elements cannot be adjusted. The quantitative push of powder is usually configured by stirring blades or vibrating feeding plus a single gravity weighing device. The stirring blade motor structure often has problems such as blades squeezing powder and powder hiding under the blades, resulting in poor powder discharge and a large amount of residual powder. Since the single gravity weighing device cannot calibrate and feedback the weight of the powder, it is impossible to make more precise adjustments to control the accuracy of the vibration feeding, and high-precision configuration cannot be achieved.

[0033] Example

[0034] Combination Figure 2 As shown, this embodiment provides a configuration mechanism, including a main control module, and also includes a detachable sealed asymmetric storage bin 3, and a vibrating weighing feeding and charging device 4 arranged below the storage bin 3 and electrically connected to the main control module;

[0035] The vibrating weighing feeding and loading device 4 includes a detachable trough 5, a first weight sensor 6 placed under the trough 5, a vibration driving module for driving the trough 5 and the first weight sensor 6 to vibrate synchronously, a detachable overturning hopper 8 arranged below the discharge port of the trough 5, and a detachable filling hopper 9 and a second weight sensor 7;

[0036] The first weight sensor 6 is used to weigh the weight of the powder discharged from the trough 5; the tipping hopper 8 is used to receive the powder discharged from the trough 5; the second weight sensor 7 is used to weigh the weight of the powder on the tipping hopper 8; and the filling hopper 9 is used to allow the powder to fall into the container.

[0037] The vibrating weighing feeding and loading device 4 is used to avoid the problem of powder agglomeration, extrusion and pipe blockage during the transmission and configuration process; two weight sensors are set to calibrate and feedback the weight of the powder, and then more finely adjust and control the accuracy of vibration feeding to achieve high-precision configuration.

[0038] Specifically, in this embodiment, Figure 2 As shown, the trough 5 is tubular, one end of which is provided with an opening for receiving the material dropped from the storage bin 3, and the other end is provided with the discharge port; the tubular trough 5 can effectively avoid the dust of the powder, and also avoid pollution and the loss of powder during vibration feeding, which may cause the accuracy of feeding to decrease. The discharge end of the trough 5 is tilted upward, and the tilt angle is 5-12 degrees; the tilted setting can better control the accuracy of feeding. A material level switch 12 is also provided on the lower side of the storage bin 3, which is used to detect whether the amount of powder in the storage bin 3 needs to be replenished, and it is electrically connected to the main control module.

[0039] The storage bin 3 adopts a sealed and asymmetric structure, which effectively prevents powder from bridging, arching, and moisture absorption, and realizes smooth and uniform material discharge; the discharge port of the storage bin 3 is connected to the opening of the material trough through a flexible tube, and the flexible tube can better adapt to the vibration of the vibrating weighing feeding and charging device 4, avoiding the hard pipe material from colliding during vibration and affecting the vibration operation.

[0040] This embodiment provides a high-precision fully automatic individualized medical formula food preparation machine, combined with Figures 1 to 4As shown, it includes a main control module, a workbench with multiple workstations, and a conveying device for conveying containers to each workstation, wherein the container is a filling bag 10 or a filling bottle, and also includes a labeling mechanism 1, multiple configuration mechanisms, a cap preparation mechanism, and a cap screwing mechanism, which are electrically connected to the main control module and sequentially arranged at each workstation; a movable clamping mechanism 11 is arranged on the conveying device to adapt to containers of different calibers.

[0041] The setting of the automated multi-station realizes the automatic configuration of the nutritional powder according to the formula, without the need for manual weighing and configuration, reducing labor costs and improving configuration efficiency. At the same time, it also avoids the continuous long-term exposure of the powder to cross-operation during manual configuration, causing food contamination, and realizes individual configuration; due to the characteristics of the powder, if a push method is adopted, such as rotating blade feeding, it will cause the powder to be squeezed and cause agglomeration, and the powder surface under the blade will be hidden, resulting in poor powder discharge and a large amount of residual powder; while the use of a vibrating weighing feeding and loading device 4 avoids the problem of agglomeration and powder hiding during the transmission and configuration process of the powder. At the same time, the setting of the detachable storage bin 3, the trough 5, the flip hopper 8, and the filling hopper 9 is convenient for cleaning and maintenance.

[0042] Two weight sensors are set up, the first weight sensor 6 is used to measure the weight of the powder discharged from the trough 5 online; the second weight sensor 7 is used to weigh the weight of the powder on the tipping hopper 8; then it is compared with the discharge weight obtained by the first weight sensor 6 to realize the calibration and feedback of the discharge powder weight, and then the accuracy of vibration discharge is more finely adjusted to achieve high-precision configuration; specifically, when the trough 5 conveys materials, the load value q per unit length on the trough 5 is measured by the first weight sensor 6; at the same time, the main control module obtains the running speed V of the material on the trough 5 at the same time; the load value q is multiplied by the running speed V to obtain the instantaneous flow rate of the material; then Then, the instantaneous flow rate of the material is accumulated and calculated to obtain the cumulative flow rate, and it is determined whether the accumulated amount reaches the preset flow rate value; the preset flow rate value refers to the amount of powder required in the formula; finally, when the preset flow rate value is reached, the weight measured by the second weight sensor 7 is combined to control the tipping hopper 8 to flip so that the powder falls into the container; and the weight measured by the second weight sensor 7 will be fed back to the main control module and compared with the preset flow rate value. When the weight measured by the second weight sensor 7 is less than the preset flow rate value, the running speed of the trough 5 is adjusted to increase; when the weight measured by the second weight sensor 7 is greater than the preset flow rate value, the running speed of the trough 5 is adjusted to decrease. It should be noted that the setting of two weight sensors can realize pre-adjustment before formula configuration to ensure the accuracy during configuration; at the same time, calibration and feedback are also carried out from time to time during configuration to realize automatic adjustment and further ensure the accuracy of configuration.

[0043] In this embodiment, the conveying device is provided with a lifting mechanism; the overturning hopper 8 is placed in the filling hopper 9; the feeding port of the material trough 5 is placed in the upper opening of the filling hopper 9; the lifting mechanism is used to place the lower opening of the filling hopper 9 in the opening of the container during filling. Avoid the dusting of powder during the feeding and filling process. It should be noted that the dusting mentioned above refers to the situation where powder is scattered during the preparation process.

[0044] In this embodiment, a concentration temperature preparation adjustment mechanism 13 is also provided at the upper station of the cover preparation mechanism, which is used to adjust the concentration and temperature of the container configured with the powder according to the formula requirements and pump the solution into it. The concentration temperature preparation adjustment mechanism 13 is a reverse osmosis heating integrated water purifier, which can control the temperature of the water outlet, and then inject the required amount of water into the container through the injection pump 14 controlled by the main control module for the formula that needs to be prepared.

[0045] Preferably, a plurality of stations of the configuration mechanism are provided, which are divided into a micro-filling station 23, a medium-filling station 24 and a large-filling station 25; the feeding rate of the vibrating weighing feeding and charging device 4 in the micro-filling station 23 is 100-300g / min; the feeding rate of the vibrating weighing feeding and charging device 4 in the medium-filling station 24 is 300-800g / min; the feeding rate of the vibrating weighing feeding and charging device 4 in the large-filling station 25 is greater than or equal to 800g / min. Specifically, in the present embodiment, 10 filling stations are included, including 3 micro-filling stations 23, whose storage bins 3 have a volume of 1L; 3 medium-filling stations 24, whose storage bins 3 have a volume of 1.5L; and 4 large-filling stations 25, whose storage bins 3 have a volume of 2L. The above can meet most of the formulation requirements, and the workstations are reasonably set up, and the workstations are divided into micro filling stations 23, medium filling stations 24 and large filling stations 25, which greatly improves the configuration efficiency and weighing accuracy. Of course, in other embodiments, more filling stations can be set according to actual needs.

[0046] In this embodiment, the vibration drive module adopts a same-frequency sinusoidal displacement vibration motor drive module to control the sinusoidal displacement to achieve more precise movement (especially at very low amplitudes), and a consistent throwing angle can keep the material at a constant speed over the entire length of the trough 5. The consistent throwing angle can keep the material flow thickness constant with high precision, ensuring the controller's rapid response to mass flow adjustment, thereby improving metering accuracy. The first weight sensor 6 adopts a resistive strain gauge weighing sensor.

[0047] Preferably, a bag blowing mechanism 2 is provided at the next station of the labeling mechanism 1 for blowing air into the bagged container to avoid the bag body of the filling bag 10 from sinking inward during filling, causing the powder to be unable to smoothly enter the bag body and causing the powder to overflow.

[0048] In this example, the container is a filling bag 10 as an example; the high-precision fully automatic individualized medical formula food preparation machine has workstations arranged in a circumferential direction, including a bagging area 20, a labeling area 21, a bag blowing area 22, a filling area, a water injection area 26, a cap preparation area 27, a cap screwing area 28 and a finished product area 29; the following describes its working process:

[0049] First, according to customer needs, the container (filling bag 10 or filling bottle) is automatically placed on the conveying device, and the container is clamped and fixed by the movable clamping mechanism 11; then the formula label is pasted on the container by the labeling mechanism 1, and then the bag is blown up by the bag blowing mechanism 2 in the bag blowing area 22; then it is transmitted to the configuration area, and the container is transmitted to the workstation where each corresponding powder configuration mechanism is located according to the formula information, and the powder is unloaded and loaded; then for the formula that requires liquid preparation, the container with the configured powder is transmitted to the water injection area 26, and the filling bag 10 is prepared with liquid through the concentration and temperature preparation adjustment mechanism 13; and for the formula that does not require liquid preparation, the workstation of the water injection area 26 is skipped and directly transmitted to the cover preparation area 27, and the cover preparation mechanism places the cover on the container mouth; then it continues to be transmitted to the cap screwing area 28, and the cap screwing mechanism performs the cap screwing operation; finally, it is transmitted to the finished product station to complete the entire configuration operation.
