Background

The weighing, subpackaging and packaging of the medicines are important links in medicine production and are links for isolating the medicines from the outside through inner packaging materials. The medicine package provides protection, classification and description for the medicine in the processes of transportation, storage, management and use, and the process requires selecting proper packaging materials or containers and adopting proper packaging technology to carry out processing such as sub-packaging, labeling and the like on the medicine or the pharmaceutical preparation.

The prior art discloses some equipment for weighing, subpackaging and packaging medicines. For example, CN212125701U (CN202020151141.4) discloses a rapid and accurate Chinese herbal medicine dispensing device, which comprises a dispersing and dedusting device, a rapid distribution device, an accurate distribution device, a weighing device and a transportation device, wherein the dispersing and dedusting device comprises a transportation rail with a mesh structure in the middle, a mesh enclosure is arranged above the transportation rail, and a blowing mechanism for blowing air from bottom to top is arranged below the mesh structure. It is believed because this utility model adopts quick distributor and accurate distributor to carry out the material supply to the weighing device on the baling line simultaneously, also improves material supply precision when guaranteeing material supply efficiency, further sets up dispersion dust collector at the material supply front end, not only can break up the medicine of stoving, makes its supply more accurate, breaks up impurity and the medicine bits in the process can detach the medicine simultaneously, improves the quality of processing chinese herbal medicine sliced medicinal herbs.

In the case of granular or powdery medicines, the granular or powdery medicines are required to be subpackaged and packaged by subpackaging equipment in the medicine preparation process. Tablet or capsule dosage forms are generally directly dispensed by a packaging machine, but bulk or large dose powder or granule formulations lack relevant weighing equipment.

For a powder composition with a large dose, the proportion of individual components may be quite small, while the proportion of some components is quite large, and the problem directly caused by the great difference of the proportions of the components is that the small proportion of the components cannot be uniformly mixed, so that the finally packaged medicine presents the problem of uneven dose.

In addition, the overall cost added by the mixing process of the composition with large different proportions is relatively high, especially for the powder with large dosage, because the capacity of the mixing equipment is fixed, and dosage units which can be produced by mixing one batch for the powder with large dosage are less, so that the production efficiency of the medicine is severely limited by a production process with not high technological content.

The compound polyethylene glycol electrolyte powder is a composition with components in large different proportions as described above, and a typical formula proportion comprises the following materials in each minimum package: 59g polyethylene glycol 4000, 1.46g sodium chloride, 5.85g anhydrous sodium sulfate, 0.7g potassium chloride, 1.75g sodium bicarbonate. The polyethylene glycol content was 59g, and the sum of the other materials was only about 9.7 g. Even if a lot of time is spent to uniformly mix materials, the yield of subpackage production after a batch of materials are uniformly mixed by a mixer is quite limited, and the problem of serious uneven mixing is not solved. The individual manufacturers respectively pack the materials in different bags, and then the different bags are combined and packed into a single dose medicament to be provided for patients, which not only greatly increases the cost of production enterprises, but also inevitably brings serious inconvenience to the patients. For example, there is a commercially available compound polyethylene glycol electrolyte powder (specification i) packed in three bags: each bag comprises 68.56g, wherein the first bag comprises 1.46g of sodium chloride and 5.68g of anhydrous sodium sulfate, the second bag comprises 0.74g of potassium chloride and 1.68g of sodium bicarbonate, and the third bag comprises 59g of polyethylene glycol 4000; and compound polyethylene glycol electrolyte powder (specification II) packed in three bags: each bag contains 137.15g, wherein the first bag contains 2.93g of sodium chloride and 11.37g of anhydrous sodium sulfate, the second bag contains 1.48g of potassium chloride and 3.37g of sodium bicarbonate, and the third bag contains 118g of polyethylene glycol 4000.

Therefore, the manipulator 33 loads the emptied material receiving hoppers 2 one by one on the first fixed clamping seat 11 at the starting end of the C-shaped horizontal conveyor belt 1, the fixed clamping seats 11 move forwards along the horizontal conveyor belt 1, and when the loading quantity of the emptied material receiving hoppers 2 is the same as the number of the weighing hoppers of the first material weighing hopper group 4, all the weighing hoppers of the first material weighing hopper group 4 pour the weighed first powder or granular medicine into each empty material receiving hopper 2 below the weighing hoppers respectively; the receiving hoppers 2 which receive the first powder or granule medicines continue to move forward one by one to reach the terminal end of the C-shaped horizontal conveyor belt 1, and when the number of the receiving hoppers is the same as that of the second material weighing hopper group 5, all weighing hoppers of the second material weighing hopper group 5 respectively dump the weighed second powder or granule medicines into the receiving hoppers 2 below the receiving hoppers which are added with the first powder or granule medicines; the hopper 2 filled with the first powder or granule medicine and the second powder or granule medicine is gripped one by the robot 33 and transferred to the packaging machine 6.

In an exemplary embodiment of the high-speed weighing dispensing and packaging machine of the present application, an even number of robot arms 32 are symmetrically extended in a star shape from the top end of the rotary shaft 31 toward the horizontal direction. The design of the robot arms 32 in an even number is advantageous for the design and operation of the apparatus and more conveniently in a symmetrical manner, in particular, when, for example, the robot arm 33 of one robot arm 32 loads a emptied hopper 2 onto the first stationary cassette 11 at the beginning of the C-shaped horizontal conveyor 1, the robot arm 33 at the other end corresponding to the robot arm 33 just picks up the hopper 2 filled with the first powder or granule medicine and the second powder or granule medicine for transfer to the packaging apparatus 6.

In an exemplary embodiment of the high-speed weighing and dispensing packaging machine of the present application, 6 to 12 mechanical arms 32 are extended from the top end of the rotating shaft 31 in a star shape symmetrically in the horizontal direction.

In an exemplary embodiment of the high-speed weighing and dispensing packaging machine of the present application, 6 to 10 robot arms 32 are extended from the top end of the rotating shaft 31 in a star shape symmetrically in the horizontal direction.

In an exemplary embodiment of the high-speed weighing and dispensing packaging machine of the present application, 8 robot arms 32 are extended from the top end of the rotary shaft 31 in a star shape symmetrically in the horizontal direction.

In an exemplary embodiment of the high-speed weighing dispensing and packaging machine of the present application, the robot arm 33 is rotatably provided in a direction of 180 to 360 ° with the extending direction of the robot arm 32 being the axial direction. Therefore, when the receiving hopper 2 is filled with the first powder or granule medicine and the second powder or granule medicine and then is grabbed by the manipulator 33 and moves to the station of the packaging equipment 6, the receiving hopper 2 rotates 180 degrees to pour the medicines into packaging materials (such as packaging bags), after the medicines are poured, the receiving hopper 2 continues to rotate 180 degrees or rotates 180 degrees reversely until the bottom latch 21 of the receiving hopper 2 faces downwards, and continues to move to the position of the fixed latch 11 at the starting end of the C-shaped horizontal conveyor belt 1 and is matched with the fixed latch.

In one exemplary embodiment of the high speed weigh dispensing and packaging machine of the present application, wherein material buffer bin 43/53 is used to load the material to be weighed dispensed and cause the vibration of the material via vibratory chute 42/52 to reach into hopper 41/51. The powder or granule medicine can be weighed more accurately by the vibration of the vibration groove 42/52.

In an exemplary embodiment of the high-speed weighing dispensing and packaging machine of the present application, the hopper 2 on the C-shaped horizontal conveyor belt 1 is rotated in the same direction as the robot arm 32. For example, as shown in fig. 1, the receiving hopper 2 and the robot arm 32 both rotate in a counterclockwise direction, but both may rotate in a clockwise direction.

In one exemplary embodiment of the high-speed weighing dispensing packaging machine of the present application, a packaging material (e.g., package bag) supply arm 61 is provided on the packaging device 6. The supply arm 61 is capable of receiving the first powder or granule medicine and the second powder or granule medicine poured from the hopper 2 into the packaging material; further, the supply arm 61 can continue to seal the packaging material around the medicine, thereby completing the weighing, dispensing and packaging operations of the powder or granule medicine.

In one exemplary embodiment of the high speed weighing dispensing packaging machine of the present application, the supply arm 61 on the packaging device 6 is counter-rotating to the robotic arm 32.

Taking the number of the mechanical arms 32, the number of the weighing hoppers 41 of the first material weighing hopper group 4, and the number of the weighing hoppers 51 of the second material weighing hopper group 5 as 8 as examples, when the high-speed weighing and subpackaging packaging machine is started, the receiving hopper 2 is fully distributed at each set station (namely, the fixed clamping seat 11) of the operation surface on the horizontal conveyor belt 1. The first powder or granular medicine (which may be referred to as material a in this application) is loaded according to a set weight into the empty receiving hopper 2 at the first 8 fixed clamping seats 11 of the start end of the C-shaped horizontal conveyor 1 and is guaranteed by a simple algorithm not to be repeatedly loaded and unloaded.

The second powder or granular medicine (which may be referred to as material B in this application) is loaded according to a set weight into the receiving hopper 2 loaded with the first powder or granular medicine at the last 8 fixed clamping seats 11 at the terminal end of the C-shaped horizontal conveyor belt 1, and a simple algorithm is used to ensure that the loading and unloading are not repeated. The moving time of the conveyor belt moving one station at a time can be 0.75 second, the stopping time is 0.75 second, and after one round of operation, two materials are loaded in the receiving hopper 2 of the last station at the tail end of the C-shaped horizontal conveyor belt 1; then, the manipulator 33 of the rotating mechanism 3 picks up the last receiving hopper 2 full of materials, and simultaneously the manipulator 33 at the opposite position of the rotating mechanism 3 puts an empty receiving hopper 2 on the vacant position of the first fixed clamping seat 11 at the starting end of the C-shaped horizontal conveyor belt 1; in addition, the manipulator 33 which grabs the full receiving hopper 2 rotates to the packaging equipment 6, at the packaging material (such as packaging bag) prepared by the packaging equipment 6, the manipulator 33 overturns the receiving hopper 2 for 180 degrees to perform blanking, and the empty receiving hopper 2 after blanking overturns for 180 degrees to return to the right position, and continues to go to the vacant position of the first fixed clamping seat 11 at the starting end of the C-shaped horizontal conveyor belt 1. The uninterrupted operation is repeated in such a way so as to completely implement the workflow of the equipment.

The compound polyethylene glycol electrolyte powder can be clinically used for treating constipation, fecal infarction, fecal stasis, intestinal gas spasm and flatulence, and can also be used for vertical enema, colon purgative or colon cleaning. The commercially available compound polyethylene glycol electrolyte powder is a powder composition containing polyethylene glycol and electrolyte, and the powder composition comprises the following components: polyethylene glycol, sodium chloride, potassium chloride, sodium bicarbonate, anhydrous sodium sulfate, powdered essence and aspartame. The powder composition, in parts by weight per 6000 parts by weight of polyethylene glycol, wherein: the amount of the sodium chloride is 118-178 parts; the amount of the potassium chloride is 60-90 parts; the amount of the sodium bicarbonate is 137-205 parts; the amount of anhydrous sodium sulfate is 461-692 parts; the amount of the powder essence is 19-29 parts; and/or aspartame in an amount of 5-7.6 parts. The compound polyethylene glycol electrolyte powder contains polyethylene glycol up to about 59g per minimum dose package and the total amount of the remaining components is less than 10g, it is difficult to uniformly mix the components having small proportions in the product, and since the mixing equipment of pharmaceutical companies is easily limited, the yield per mixing batch is rather limited if the materials are subjected to total mixing. The medicine is taken orally after being dissolved in water, and the dissolution is one excellent mixing process, and has no incompatibility among the components, so that polyglycol is used as one material while other components are mixed to form the other material. For example, CN102805752A (2012102957225) relates to a compound polyethylene glycol electrolyte powder, and the preparation method thereof is as follows: a) respectively crushing sodium chloride, potassium chloride, sodium bicarbonate, anhydrous sodium sulfate, powdered essence and aspartame, and sieving with a sieve with the pore diameter of less than 24 meshes (preferably less than 50 meshes, preferably less than 65 meshes); b) pulverizing polyethylene glycol, and sieving with sieve with pore diameter smaller than 24 mesh (preferably smaller than 50 mesh, preferably smaller than 65 mesh); c) mixing the powder of the step a) according to the formula ratio to obtain electrolyte mixed powder; d) separately and sequentially or simultaneously packaging the electrolyte mixed powder of the step c) and the polyethylene glycol powder of the step b) into packaging containers to obtain a powdery composition. In a typical example of the compound polyethylene glycol electrolyte powder provided by CN102805752A (2012102957225), the prescription is: 6000 parts of polyethylene glycol, 140 parts of sodium chloride, 70 parts of potassium chloride, 175 parts of sodium bicarbonate, 585 parts of anhydrous sodium sulfate, 25 parts of pineapple powder essence and 6 parts of aspartame; the preparation method comprises the following steps: mixing the crushed and 80-mesh sodium chloride, potassium chloride, sodium bicarbonate, anhydrous sodium sulfate, pineapple powder essence and aspartame to obtain an inorganic salt raw material mixture, feeding the inorganic salt raw material mixture and the crushed and 65-mesh polyethylene glycol PEG into two feed hoppers respectively, and packaging into a packaging bag to obtain the finished product. The apparatus of the present application was tested using the above recipe and preparation method unless otherwise stated.

The application discloses high-speed partial shipment packagine machine that weighs is a section high-speed equipment for packing of weighing, can weigh multiple material fast simultaneously and pack, and the main occasion that is applied to the symmetry required precision height, fast. The high-speed weighing and subpackaging packaging machine can improve the production efficiency, and the weighing number of each minute reaches 40 times and far exceeds the like products. The high-speed weighing and subpackaging packaging machine is high in metering precision, and the metering precision can reach +/-0.2 g of high-precision level. The high-speed weighing, subpackaging and packaging machine is suitable for weighing all dry powder or granular materials with high requirement precision. The weighing, subpackaging and packaging equipment popular in the market at present generally has the weighing speed of about 25 times per minute, and the weighing precision of most of equipment is +/-0.5 g. When the high-speed weighing and subpackaging packaging machine is designed with 8 mechanical arms 32 under the condition that carbon dioxide is not blown, the weighing speed per minute can easily reach 40 times, and the metering precision reaches +/-0.2 g; when the device is designed with 8 mechanical arms 32 in the condition of purging carbon dioxide, the weighing speed per minute can easily reach 37 times and the metering precision reaches +/-0.2 g.

When the compound polyethylene glycol electrolyte powder is subpackaged by using the method, the materials are treated in the following way: 59g of polyethylene glycol 4000 is used as a first part material, namely a first powder or granule medicine; 1.46g of sodium chloride, 5.68g of anhydrous sodium sulfate, 0.74g of potassium chloride and 1.68g of sodium bicarbonate were premixed to obtain 9.56g of a premix of the other materials as a second part of the material, i.e., a second powder or granule.

The medicine to be subpackaged is compound polyethylene glycol electrolyte powder, and the typical formula proportion of the medicine to be subpackaged is that the materials contained in each minimum package are as follows: 59g of polyethylene glycol 4000, 1.46g of sodium chloride, 5.68g of anhydrous sodium sulfate, 0.74g of potassium chloride and 1.68g of sodium bicarbonate. 59g of polyethylene glycol and only about 9.56g of other materials are added, so that the problem of low mixing efficiency caused by great difference of the mixture amount when all the materials are mixed together is solved, the polyethylene glycol 59g is used as a first part of materials (namely first powder or granular medicine), and 9.56g of other materials are premixed and used as a second part of materials (namely second powder or granular medicine), and the first part of materials and the second part of materials are respectively and sequentially filled into the receiving hopper 2 through the first material weighing hopper group 4 and the second material weighing hopper group 5.

It is advantageous to fill the receiving hopper 2 with 59g of polyethylene glycol first by means of the first material-weighing hopper group 4 and then with 9.56g of the other premixed material by means of the second material-weighing hopper group 5, this sequential filling being effected; the reason is that when 9.56g of the other premix is first filled into the receiving hopper 2 and then 59g of the large-volume material is filled, 9.56g of the small-volume material is flushed up by the impact force of the large-volume material to generate drug dust; in reverse, 9.56g of a small volume of 59g of the bulk material was filled first and did not produce any drug dust due to impact.

The inventors of the present application have found that after the receiving hopper 2 is filled with 59g of polyethylene glycol and then with 9.56g of other premixed materials, and the receiving hopper 2 is operated to the packaging device 6 to empty all the materials, the residual medicinal powder adhered to the inner wall of each receiving hopper 2 reaches 0.83g or more (148 times of packaging operation, the residual medicinal powder (mean ± SD) is 0.887g ± 0.064), and the residual medicinal powder is mainly polyethylene glycol, although the clinical therapeutic effect is not seriously affected by the residue, which is a process defect that the skilled person in the art does not wish to encounter. It has been unexpectedly found that when the empty receiving hopper 2 is filled with carbon dioxide gas (3-4 seconds, pressure 0.5 mPa; in the present invention, if not otherwise stated, the carbon dioxide blower is used to purge the empty receiving hopper with pressure 0.5mPa for 3-4 seconds during the specific dispensing operation; of course, the purging conditions can be adjusted as required in the production practice), the powder residue can be significantly reduced to below 0.16g (the statistical residual powder (mean value ± SD) of 164 dispensing operations is 0.117g ± 0.013), which is not at all predictable in the prior art.

In the case where the hopper is not purged with carbon dioxide, if 59g of the first powder or granule medicine is filled into the hopper 2 by the first material hopper group 4 and 9.56g of the first powder or granule medicine is filled into the hopper 2 by the second material hopper group 5, the powder residue reaches about 0.86g (the total of the residual powder (mean value ± SD) of 152 separate-charging operations is 0.862g ± 0.073). In the case where the hopper is not purged with carbon dioxide, if 59g of the second powder or granule medicine is filled into the hopper 2 by the first material hopper group 4 and 9.56g of the second powder or granule medicine is filled into the hopper 2 by the second material hopper group 5, the powder residue reaches about 0.12g (the total of the residual powder (mean value ± SD) of 152 separate-charging operations is 0.123g ± 0.011). This indicates that this adhesion is due to polyethylene glycol.

The above-described embodiments are merely preferred embodiments for fully illustrating the present application, and the scope of the present application is not limited thereto. The equivalent substitution or change made by the person skilled in the art on the basis of the present application is within the protection scope of the present application. The protection scope of this application is subject to the claims.
