Description

Technical Field

[0001] The present disclosure relates to the technical field of unpacking bagged food and pharmaceutical-grade powder materials, and in particular to a method for unpacking and discharging food and pharmaceutical-grade bagged powder materials and a food and pharmaceutical material processing system. Background Art

[0002] Generally speaking, the packaging of food and pharmaceutical-grade bagged powders is more stringent than that of other industries, typically consisting of an outer bag and an inner bag. During the food and pharmaceutical production process, unpacking of the bagged powders is often necessary. First, the outer packaging of the bagged powders is removed, exposing the inner bag. The unpacked bags are then placed on a dust removal vehicle. The vehicle is then placed in a dust removal room for static dust removal, effectively removing dust from the inner bags. This effectively removes dust from the inner bags, completing the dust removal process. The bagged powders are then loaded into the bag-breaking area via an automatic loading device. Finally, a bag-breaking machine is used to break the bag, allowing the powders to be delivered to the corresponding unloading stations, completing the unpacking and unloading process.

[0003] However, common food and medicine are generally obtained by compounding a variety of different types of materials. Since the food and medicine grade bagged powders without the outer packaging are basically the same color, it is easy for different types of materials to be confused, causing the automatic feeding device to easily load the wrong material. In order to avoid the automatic feeding device loading the wrong material, some scholars believe that: a material identification method can be added to the automatic feeding device. For example, Chinese patent document No. CN112464967A discloses a material identification method. At the same time, in conjunction with the photo recognition technology, it can identify the label of the food and medicine grade bagged powder and load it, so as to reduce the probability of the automatic feeding device loading the wrong material.

[0004] However, since most labels are currently attached to the outer wall of the inner bag, when multiple bags of food and drug grade bagged powder are placed on the dust removal vehicle, the adjacent food and drug grade bagged powder will block the labels of the adjacent food and drug grade bagged powder, such as Figure 1 As shown, the camera module cannot recognize the material, and the problem of material loading error still exists.

[0005] Some scholars also believe that the label can be attached near the tie of the inner bag of the package. However, due to the influence of the tie, the label will be wrinkled. Figure 2 At this time, some scholars believe that the food and drug grade bagged powder can be placed flat on the dust removal vehicle, so that the label can be facing upward and completely exposed, thus effectively solving the above-mentioned problem of label obstruction and wrinkled label that is not conducive to photo identification.

[0006] Although the food and drug grade bagged powder lies flat on the dust removal vehicle, it is convenient for taking photos and identifying labels. However, since the filling volume of the food and drug grade bagged powder is not full, such as Figure 1 and Figure 2 As shown, the food and drug-grade bagged powder will move within the packaging bag. When the food and drug-grade bagged powder is placed on the dust removal vehicle, a flat label cannot be obtained. In this case, it needs to be leveled, which is a cumbersome operation. In addition, because the area of ​​the flat food and drug-grade bagged powder is larger than that of the upright food and drug-grade bagged powder, the dust removal vehicle can accommodate fewer food and drug-grade bagged powders under the same unit conditions, resulting in lower dust removal efficiency per dust removal vehicle. Summary of the Invention

[0007] The purpose of the present invention is to overcome the shortcomings of the existing technology and provide a method for unpacking and unloading food and pharmaceutical grade bagged powder and a food and pharmaceutical material processing system that ensures the accuracy of loading and simple loading operation while ensuring that the single dust removal efficiency of the dust removal vehicle is not reduced.

DETAILED DESCRIPTION

[0044] In order to facilitate the understanding of the present disclosure, the present disclosure will be described more fully below with reference to the related drawings. The preferred embodiments of the present disclosure are shown in the drawings. However, the present disclosure can be implemented in many different forms, and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present disclosure more thorough and comprehensive.

[0045] It should be noted that when an element is referred to as being "on" another element, it can be directly on the other element or intervening elements can also be present. Where an element is referred to as being "connected" or "coupled" to another element, it can be directly connected or coupled to the other element or intervening elements can also be present. The terms "vertical", "horizontal", "left", "right" and similar expressions as used herein are for illustrative purposes only and are not intended to be limiting.

[0046] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. The terminology used in the description of the disclosure herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the disclosure. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0047] Please refer to Figure 3 In order to better understand the technical solutions and beneficial effects of the disclosure, the disclosure will be further described in detail below in combination with specific embodiments. A food and drug grade bagged powder unpacking and discharging method of an embodiment includes part or all of the following steps:

[0048] S101, different kinds of food and drug grade bagged powder are obtained. It can be understood that since there are many kinds of materials in the formula of general food and drugs, when the user can prepare materials according to the formula of food and drugs, a plurality of different kinds of food and drug grade bagged powder will be obtained; in order to prepare for production.

[0049] S102, the outer packaging of each food and drug grade bagged powder is removed, so that the packaging inner bag and the cable tie of the food and drug grade bagged powder are exposed; wherein the food and drug grade powder of the food and drug grade bagged powder is not completely filled; different kinds of food and drug grade bagged powder use cable ties of different colors to tighten and fix the packaging inner bag, and the colors of the cable ties of the same kind of food and drug grade bagged powder are the same.

[0050] It can be understood that by removing the outer packaging of each bag of food and drug grade bagged powder, the packaging inner bag and the cable tie of the food and drug grade bagged powder can be exposed, so that on the one hand, the dust on the outer surface of the food and drug grade bagged powder can be effectively removed, that is, the outer packaging bag is removed; on the other hand, it is convenient for subsequent more comprehensive dust removal operation on the surface of the packaging inner bag to ensure that the food and drug grade bagged powder can reach the cleanliness required for production; on the other hand, the exposed cable tie is convenient for subsequent photographing and identification to accurately obtain the feeding information.

[0051] It should be noted that since the food and pharmaceutical grade bagged powder is not completely filled with food and pharmaceutical grade powder, a certain gap is left in the food and pharmaceutical grade bagged powder. The remaining gap can not only effectively avoid the problem of packaging bag breakage of food and pharmaceutical grade bagged powder during transportation, but also avoid the phenomenon of bag bulging of food and pharmaceutical grade bagged powder, thereby providing better product quality for food and pharmaceutical grade bagged powder. However, the gap left behind will cause many wrinkles to form in the tie area of ​​the inner bag, which limits the label attachment position. This is mainly reflected in three aspects: if the label is attached to the tie area before it is tied, the label will wrinkle as it is tied, making it impossible to fully identify the graphic information on the label, and there is still the problem of loading errors; if the label is attached after it is tied, the many wrinkles will reduce the connection strength between the label and the wrinkles, causing the label to easily fall off when the user removes the outer packaging, resulting in a greater probability of loading errors; if the label is attached to the outer wall of the inner bag, the adjacent food and drug grade bagged powder will block the label of the adjacent food and drug grade bagged powder during the dust removal process, which still affects the problem of camera identification. In addition, because the food and drug grade bagged powder removed from the outer packaging is basically the same color, different types of materials are easily confused, resulting in the problem of loading the wrong material.

[0052] Therefore, in the present disclosure, different types of food and pharmaceutical grade bagged powders are fastened and fixed with cable ties of different colors, and the cable ties of the same type of food and pharmaceutical grade bagged powders are of the same color, so that different types of food and pharmaceutical grade bagged powders can obtain different loading information, while the same type of food and pharmaceutical grade bagged powders can obtain the same loading information, to ensure that the loading device performs the loading operation according to the loading information, thereby ensuring that each bag of food and pharmaceutical grade bagged powders can be accurately distributed to the corresponding bag breaking station, effectively avoiding the problem of wrong material loading in traditional food and pharmaceutical grade bagged powders that have been removed from the outer packaging because the inner bags of the packaging are the same color. It is particularly suitable for applications where the food and pharmaceutical grade bagged powders are not completely filled and the inner bags of the packaging are all the same color.

[0053] S103, placing each of the food and drug grade bagged powders upright on a dust removal vehicle, with the cable ties of different colors exposed.

[0054] It can be understood that if the food and drug grade bagged powder is placed on the dedusting vehicle, the food and drug grade powder in the food and drug grade bagged powder will move in the inner bag of the package, resulting in that the food and drug grade bagged powder after being placed cannot obtain a label with high flatness. Therefore, the user needs to additionally perform a flattening operation on the food and drug grade bagged powder after being placed, and there is a problem of complicated operation. In addition, since the area of the food and drug grade bagged powder in a lying state is larger than that of the food and drug grade bagged powder in a standing state, the number of food and drug grade bagged powders placed by the dedusting vehicle under the same unit condition is reduced, and the single dedusting efficiency of the dedusting vehicle is reduced.

[0055] Therefore, in the present disclosure, by vertically placing each food and drug grade bagged powder on the dedusting vehicle, the different colored ties are exposed, and the exposed ties facilitate subsequent photographing and identification. In this way, without the need for placing and flattening the food and drug grade bagged powder, the accuracy of feeding and the simplicity of feeding operation are ensured under the condition that the single dedusting efficiency of the dedusting vehicle is not reduced.

[0056] It also needs to be noted that if the food and drug grade bagged powder is placed in a lying state during the dedusting process, the contact area of the food and drug grade bagged powder with the dedusting vehicle is large, that is, the dedusting blind area of the food and drug grade bagged powder is large. Therefore, in the present disclosure, the food and drug grade bagged powder is placed in a vertical state, which can effectively reduce the contact area of the food and drug grade bagged powder with the dedusting vehicle, so as to minimize the dedusting blind area of the food and drug grade bagged powder, thereby realizing a more comprehensive dedusting operation on the inner bag of the food and drug grade bagged powder.

[0057] S104, performing a dedusting operation on each food and drug grade bagged powder placed on the dedusting vehicle to realize a single batch dedusting operation of the dedusting vehicle, so as to maximize the minimization of the dedusting blind area of each food and drug grade bagged powder under the condition that the single dedusting efficiency of the dedusting vehicle is not reduced, thereby realizing a more comprehensive dedusting operation on the inner bag of the food and drug grade bagged powder.

[0058] S105, photographing and identifying the color of each tie to obtain feeding information of each food and drug grade bagged powder.

[0059] It can be understood that in the production of general food and drugs, there are sequence requirements for the addition of different types of materials. Therefore, the control module of the automatic feeding device will set the correct material feeding sequence according to the type of the food and drug actually produced, that is, preset the material feeding information. After the camera photographs and identifies the color of each tie, picture information is generated, and after being processed by the processing module, the feeding information can be generated.

[0060] It should be noted that since the camera takes a picture of the color of the ribbon to generate picture information, and the processing module processes the picture information to generate feeding information, both of which are prior art, therefore, in the present disclosure, they are not described in detail.

[0061] S106, the automatic feeding device executes the feeding operation according to the feeding information, so that each food and drug grade bagged powder is accurately distributed to the corresponding bag breaking station, so as to effectively avoid the phenomenon of wrong material on the automatic feeding device.

[0062] S107, the food and drug grade bagged powder is broken to deliver the food and drug grade powder to the corresponding discharging station, thereby completing the unpacking and discharging operation of the food and drug grade bagged powder.

[0063] The above-mentioned food and drug grade bagged powder unpacking and discharging method, since different types of food and drug grade bagged powder use different colored ribbons to tightly fix the inner bag of the package, and the color of the ribbon of the same type of food and drug grade bagged powder is the same, and the use of each food and drug grade bagged powder is placed vertically on the dust removal vehicle, so that the different colored ribbons of each food and drug grade bagged powder are exposed, which is conducive to subsequent photographing and identification, so as to accurately obtain the feeding information of each food and drug grade bagged powder. In this way, without the need to lay down and flatten the food and drug grade bagged powder, not only simplifies the feeding operation, but also ensures that the single dust removal efficiency of the dust removal vehicle will not be low; also maximizes the small dust removal blind area of each food and drug grade bagged powder.

[0064] Further, since different types of food and drug grade bagged powder use different colored ribbons to tightly fix the inner bag of the package, and the color of the ribbon of the same type of food and drug grade bagged powder is the same; so that different types of food and drug grade bagged powder can obtain different feeding information, while the same type of food and drug grade bagged powder can obtain the same feeding information, to ensure that the feeding device executes the feeding operation according to the feeding information, so that each bag of food and drug grade bagged powder can be accurately distributed to the corresponding bag breaking station, effectively avoiding the problem of wrong material of traditional food and drug grade bagged powder due to the same color of the inner bag of the package, especially suitable for food and drug grade powder that is not completely filled and the inner bag of the package is the same color.

[0065] In one of the embodiments, in the step of identifying the color of the strap for each bag, the step of identifying the identification part of the strap is further included to obtain the material comparison information of each bag of the food and drug grade bagged powder; the material comparison information is compared with the feeding information; when the material comparison information matches the feeding information, the control module sends the feeding information, and at this time, the automatic feeding device performs the feeding operation according to the feeding information; when the material comparison information does not match the feeding information, the control module sends the alarm information, and at this time, the automatic feeding device performs the alarm operation according to the alarm information, so that the added material comparison information can improve the accuracy of feeding and effectively avoid the phenomenon that the feeding error still exists when only the color of the strap is used to obtain the feeding information.

[0066] As shown in the drawings, Figure 4 In one of the embodiments, the strap 10 includes a fastening part 11 and a color band 12 connected together, and the identification part 13 is arranged on the side part adjacent to the tail part of the color band 12.

[0067] It can be understood that the user can set the corresponding color band 12 according to different kinds of food and drug grade bagged powder, and different colors represent different feeding information, and the same kind of food and drug grade bagged powder can use the same color of color band 12, so as to ensure that after the outer packaging of different kinds of food and drug grade bagged powder is removed, the same kind of food and drug grade bagged powder can be provided with the same color of strap 10, and different kinds of food and drug grade bagged powder use different colors for subsequent photographing and identifying.

[0068] In use, the strap 10 is wound around the inner bag of the packaging for one turn, and then the tail of the color band 12 is buckled into the fastening part 11 and is pulled tight and fixed to realize the fastening and fixing of the strap 10, so that the tail of the strap 10 can be exposed outside the sealing area. It is worth mentioning that since the color band 12 buckled into the fastening part 11 is prior art, therefore, in the present disclosure, no specific description is made.

[0069] It can also be understood that since the identification part 13 is arranged on the side part adjacent to the tail part of the color band 12, the camera can obtain the color information and the material comparison information of the strap 10 at the same time by photographing at the same position, without moving and batching, effectively improving the processing efficiency of the feeding information to better adapt to the needs of automatic production.

[0070] It can also be understood that since the added color band 12 can also provide positioning for the automatic feeding device, that is, the position of the color band 12 is the grabbing part, which is conducive to the automatic feeding device to quickly grab the food and drug grade bagged powder, effectively avoiding the empty grabbing of the automatic feeding device and affecting the feeding efficiency.

[0071] In one of the embodiments, in order to ensure that the camera can obtain the color information of the ribbon 10 and the material matching information at the same time by taking a picture at the same position, the identification part 13 is kept facing the camera during use, so that the camera can take a good picture and identify.

[0072] In one of the embodiments, the identification part 13 is a text identification part 13 or a two-dimensional code, so that the camera can obtain the material matching information of the food and drug grade bagged powder.

[0073] In a more preferred embodiment, the identification code is a two-dimensional code. It can be understood that the text of the text identification part 13 is too much to be photographed, while the two-dimensional code has a small volume and is easy to print on the side of the tail of the ribbon 12, thereby ensuring that the camera can accurately obtain the material matching information of the food and drug grade bagged powder.

[0074] It can be understood that since the food and drug grade powder of the food and drug grade bagged powder is not completely filled, when the food and drug grade powder of the food and drug grade bagged powder is vertically placed on the dust removal vehicle, the exposed direction of the ribbon 12 of the food and drug grade bagged powder will appear irregular, as shown in Figure 1 Therefore, in one of the embodiments, the base of the camera is provided with an adjusting member, which can adjust the angle of the camera, so that the camera can better scan and identify the two-dimensional code of the irregularly placed ribbon 12, thereby ensuring that the camera can accurately obtain the material matching information.

[0075] In one of the embodiments, in the step of photographing and identifying the color of the ribbon 10 of each bag, the tail of the ribbon 10 is exposed to the sealing area of the food and drug grade bagged powder, so as to be photographed and identified subsequently.

[0076] It can be understood that the conventional bag breaking machine usually adopts chain conveying to break the bag and discharge, but the gap of the chain conveying is easy to mix the food and drug grade powder, thereby affecting the utilization rate of the food and drug grade powder; and the friction of the chain conveying is large, which is easy to cause metal to fall off and cause the problem of metal residue in the food and drug grade powder material. Therefore, some scholars think that the conveying belt can be used for bag breaking and discharging, but the conveying belt has the problem of more food and drug grade powder remaining in the inner bag of the package, and the utilization rate of the food and drug grade powder is low.

[0077] Therefore, in one of the embodiments, the vibration bag breaking device 20 is used to break the bag of the food and drug grade bagged powder, so that the food and drug grade bagged powder can be broken and discharged without using chain conveying or conveying belt conveying under the action of the vibration bag breaking device 20, thereby effectively avoiding the problems of metal residue in the food and drug grade powder material or more food and drug grade powder remaining in the inner bag of the package.

[0078] AsFigures 5 to 7 As shown, in one embodiment, the bag breaking device 20 comprises a rack 21, a blade 22 and a collection box 23, the rack 21 is formed with a bag breaking vibration feeding area 211, the bag breaking vibration feeding area 211 respectively extends to the feeding conveyor belt 24 of the feeding device and the collection box 23, so that the dedusted food and drug grade bagged powder can be conveyed from the feeding conveyor belt 24 to the bag breaking vibration feeding area 211 for bag breaking operation; and since the blade 22 is arranged at one end of the bag breaking vibration feeding area 211 adjacent to the feeding conveyor belt 24, the blade 22 can break the bag of the food and drug grade bagged powder, and one end of the bag breaking vibration feeding area 211 adjacent to the collection box 23 is formed with a discharge port 2112a, the discharge port 2112a is used for communication with the lower conveying pipeline, so that the food and drug grade powder in the food and drug grade bagged powder can be conveyed to the discharge port 2112a under the action of vibration, and then flow into the lower conveying pipeline, thereby conveying the food and drug grade powder in the food and drug grade bagged powder to the corresponding lower conveying station.

[0079] It can be understood that, since the food and drug grade powder in the food and drug grade bagged powder is not completely filled, and the feeding conveyor belt 24 is an upward conveying belt, the food and drug grade powder in the food and drug grade bagged powder is prone to accumulate on one side of the inner bag during upward conveying under the action of gravity, resulting in that the food and drug grade powder sent into the bag breaking vibration feeding area 211 is accumulated on one side, thereby being not conducive to the blade 22 to cut the inner bag, that is, the food and drug grade powder in the food and drug grade bagged powder is less when entering the initial section of the blade 22, resulting in that the blade 22 is prone to deviate when cutting the inner bag. Therefore, in one embodiment, the rack 21 is further formed with a horizontal buffer area 212, the horizontal buffer area 212 is arranged between the feeding conveyor belt 24 and the bag breaking vibration feeding area 211, so that the added horizontal buffer area 212 is conducive to buffering and adjusting the food and drug grade powder in the food and drug grade bagged powder, and cooperating with the vibration of the rack 21, so that the food and drug grade powder can be evenly distributed in the inner bag, to ensure that the food and drug grade powder in the food and drug grade bagged powder is more when entering the initial section of the blade 22, thereby ensuring that the blade 22 can cut the inner bag more quickly, and effectively avoiding the phenomenon that the blade 22 is prone to deviate when cutting the inner bag.

[0080] It is understandable that since the packaging inner bag is usually a plastic inner bag, and the plastic inner bag has a certain toughness, if the cutting force of the blade 22 is small, it is easy to cause the cut edge of the plastic inner bag to produce a phenomenon of drawing, and the food and drug grade bagged powder is vibrated, so that the food and drug grade powder will continuously rub against the cut edge during the falling process, causing the drawing to fall into the food and drug grade powder and cause the problem of drawing residue. In one embodiment, the blade 22 is rotatably set on the bag breaking vibration feeding area 211, which increases the cutting force of the blade 22, thereby ensuring that the blade 22 can quickly cut through the packaging inner bag, effectively avoiding the phenomenon of drawing at the cut edge of the plastic inner bag, and thus ensuring the quality of the food and drug grade powder bag breaking and unloading.

[0081] In order to prevent the unloading inner bag from falling into the unloading station, Figures 5 to 7 As shown, in one embodiment, the bag breaking vibration feeding area 211 includes a vibration feeding channel 2111 and a vibration conveying channel 2112 distributed from top to bottom, and the head of the vibration feeding channel 2111 is provided with the blade 22, that is, the head of the vibration feeding channel 2111 refers to the vibration feeding channel 2111 arranged adjacent to the feeding conveyor belt 24, so that the blade 22 can cut the inner bag of the package; the tail end of the vibration feeding channel 2111 refers to the vibration feeding channel 2111 arranged adjacent to the collecting box 23; so that the vibration feeding channel The tail end of the channel 2111 can be connected to the collecting box 23, so that the collecting box 23 can collect blank packaging inner bags; and since the vibration feeding channel 2111 is formed with a feeding slit 2111a, the feeding slit 2111a is connected with the vibration conveying channel 2112, and the feeding slit 2111a is used for feeding the food and pharmaceutical grade bagged powder, and for preventing the packaging inner bags from falling into the vibration conveying channel 2112; the vibration conveying channel 2112 is formed with the discharge port 2112a.

[0082] During use, when the food and drug grade bagged powder enters the head of the vibrating feeding channel 2111 under the action of vibration, the blade 22 will quickly cut the inner bag of the packaging under the action of the external driver, so that the food and drug grade powder in the inner bag of the packaging will quickly fall into the feeding narrow slot 2111a under the action of gravity and vibration, and then fall into the vibrating conveying channel 2112 through the feeding narrow slot 2111a; and the feeding narrow slot 2111a can also effectively prevent the inner bag of the packaging from falling into the vibrating conveying channel 2112 during the feeding process. As the food and drug grade bagged powder is continuously vibrated and conveyed, the food and drug grade powder in the inner bag of the packaging can fall into the feeding narrow slot 2111a more comprehensively and enter the vibrating conveying channel 2112, while the blank inner bag of the packaging will fall into the collection box 23, thereby realizing the recycling of the inner bag of the packaging.

[0083] In one embodiment, the blade 22 cuts the inner packaging bag in a direction opposite to the conveying direction of the food and pharmaceutical grade bagged powder, so as to ensure that the blade 22 can quickly cut the inner packaging bag.

[0084] In one embodiment, the blade 22 continuously cuts along the length direction of the inner packaging bag, so as to ensure that the discharge port of the food and pharmaceutical grade bagged powder is maximized, which is conducive to the food and pharmaceutical grade powder being quickly vibrated into the discharge narrow gap 2111a, and also ensures that the contact area between the food and pharmaceutical grade bagged powder and the vibration discharge passage 2111 is small, which maximally reduces the friction between the inner packaging bag and the vibration discharge passage 2111, thereby reducing the probability of generating impurities, and further ensuring the quality of the food and pharmaceutical grade powder discharge.

[0085] In one embodiment, the blade 22 is arranged at an eccentric position with respect to the width distribution position of the vibration discharge passage 2111, i.e., the blade 22 is arranged adjacent to the left side or the right side of the head of the vibration discharge passage 2111, so as to ensure that the cut opening of the food and pharmaceutical grade bagged powder cut by the blade 22 is also at an eccentric position with respect to the width distribution position of the inner packaging bag, so that the weight of the two sides of the food and pharmaceutical grade bagged powder cut by the blade 22 is greatly different, which makes the speed of the two sides of the food and pharmaceutical grade bagged powder different, i.e., forms two discharge laminar flows with different discharge speeds, effectively avoiding the problem that the food and pharmaceutical grade bagged powder cut by the blade 22 is easily blocked during discharge; and the food and pharmaceutical grade powder on one side can be quickly vibrated and discharged under the action of gravity, thereby effectively reducing the vibration energy consumption.

[0086] In one embodiment, the blade 22 is a disc blade 22, which is rotationally arranged in the vibration discharge passage 2111, and the driving end of the driver is connected with the rotating rod of the disc blade 22, so that the driver can drive the blade 22 to rotate, thereby ensuring that the disc blade 22 can comprehensively and quickly cut the inner packaging bag of the food and pharmaceutical grade bagged powder. Specifically, the driver is an electric motor or a rotary air cylinder, so as to realize the rotation of the blade 22.

[0087] In one embodiment, the axial plane of the disc blade 22 is perpendicular to the conveying direction of the food and pharmaceutical grade bagged powder, so as to ensure that the disc blade 22 can comprehensively and quickly cut the inner packaging bag of the food and pharmaceutical grade bagged powder.

[0088] It can be understood that if the eccentricity of the cutting opening of the food and drug grade bagged powder is too narrow, the weight difference between the two sides of the food and drug grade bagged powder after being cut by the blade 22 is too large, and the narrower side of the food and drug grade bagged powder after being cut by the blade 22 is easily stuck in the narrow discharge gap 2111a to cause the problem of discharge blockage. Therefore, in one embodiment, when the blade 22 cuts the inner bag of the package, the position of the blade 22 in the width distribution of the food and drug grade bagged powder satisfies the following condition: the distance from the center position of the blade 22 to the narrowest side of the food and drug grade bagged powder > the width of the narrow discharge gap 2111a, so as to ensure that the eccentricity of the cutting opening of the food and drug grade bagged powder is appropriate, and effectively avoid the problem that the narrower side of the food and drug grade bagged powder after being cut by the blade 22 is easily stuck in the narrow discharge gap 2111a to cause the problem of discharge blockage.

[0089] In a more preferred embodiment, the width of the narrow discharge gap 2111a < the distance from the center position of the blade 22 to the narrowest side of the food and drug grade bagged powder ≤ 1 / 2 the width of the inner bag of the package of the food and drug grade bagged powder, so as to better ensure that the eccentricity of the cutting opening is appropriate, to achieve faster vibration discharge of the food and drug grade bagged powder after being cut by the blade 22, while effectively reducing the vibration energy consumption, and also avoiding the problem that the narrower side of the food and drug grade bagged powder after being cut by the blade 22 is easily stuck in the narrow discharge gap 2111a to cause the problem of discharge blockage.

[0090] It should be noted that many drum unpacking machines currently usually configure a screen in the bag breaking channel. Since the screen is generally made of metal, the cut inner bag of the package is easily rubbed with the screen in the bag breaking channel to generate metal impurities and cause the problem of residual metal of the food and drug grade powder. Therefore, in the present disclosure, by adding the narrow discharge gap 2111a in the vibration discharge channel 2111, the setting of the screen is effectively avoided, so as to effectively avoid the problem that the cut inner bag of the package is rubbed with the screen to cause the residual metal of the food and drug grade powder.

[0091] It can be understood that since the cut food and drug grade bagged powder can form a funnel-shaped discharge state in the vibration discharge channel 2111 under the action of gravity, in order to better match the discharge of the cut food and drug grade bagged powder, in one embodiment, the cross-section of the vibration discharge channel 2111 is funnel-shaped, and the discharge narrow slit 2111a is set at the narrowing part of the funnel to ensure that the cut food and drug grade bagged powder can fall well on both sides of the vibration discharge channel 211 under the action of gravity. 1, and the cutting opening in the middle of the inner bag of the package is formed in an upwardly opened state in the funnel-shaped vibration discharge channel 2111, thereby increasing the cutting opening area in the middle of the inner bag of the package and accelerating the discharge speed of the food and drug grade powder in the inner bag of the package; and the middle part of the food and drug grade bagged powder falling into the funnel-shaped vibration discharge channel 2111 will bend to a certain extent, thereby ensuring that a gap can be formed between the cutting opening and the upper part of the discharge narrow slit 2111a, increasing the receiving area of ​​the cutting opening for discharging, and effectively avoiding the problem of easy blockage of the food and drug grade bagged powder.

[0092] It should also be noted that due to the use of a vibration feeding method, the side walls of the vibration feeding channel 2111 can generate micro-vibrations, which effectively reduces the friction between the packaging inner bag of the cut food and pharmaceutical grade bagged powder and the side walls of the vibration feeding channel 2111 during the vibration feeding process, thereby effectively avoiding the generation of impurities and ensuring the quality of the food and pharmaceutical grade powder discharge.

[0093] It can be understood that since the food and drug grade bagged powder that has just been cut has a large weight on both sides when it is unloaded, if the width of the unloading slit 2111a is too small, it cannot meet the demand for fast unloading of the food and drug grade powder; and since the cut food and drug grade bagged powder is conveyed to the tail end of the vibrating unloading channel 2111, the food and drug grade powder is basically unloaded at this moment, and the packaging inner bag is basically weightless at this time, that is, it is a blank packaging inner bag; and under the action of vibration, the blank packaging inner bag is easily rolled into the unloading slit 2111a to affect the quality of the food and drug grade powder unloading. Therefore, if Figure 7 As shown, in one embodiment, the width of the discharge narrow slot 2111a gradually increases from the end close to the loading conveyor belt 24 to the end away from the loading conveyor belt 24, and a closed end 2111b is formed at the end of the discharge narrow slot 2111a close to the collecting box 23. In this way, while ensuring that the vibrating discharge channel 2111 has a faster discharge speed close to the loading conveyor belt 24, the problem of blockage of food and pharmaceutical grade powder can be effectively avoided; at the same time, the closed end 2111b formed can effectively prevent the blank packaging inner bag from being rolled into the discharge narrow slot 2111a to affect the quality of the food and pharmaceutical grade powder discharge.

[0094] It can be understood that although the cut food and drug grade bagged powder is mostly finished when it is conveyed to the tail end of the vibration blanking passage 2111, there will still be a small amount of food and drug grade powder adhering to the inner bag of the package, which affects the utilization rate of the food and drug grade powder. Therefore, as shown in Figure 6 one embodiment, the closed end 2111b has an inclined surface 2111c, which is gradually inclined downward from the end close to the collection box 23 to the end away from the collection box 23. In this way, the user can extend the vibration time of the blank inner bag at the tail end of the vibration blanking passage 2111 to vibrate the small amount of food and drug grade powder adhering to the inner bag of the package to the inclined surface 2111c, and under the action of vibration, the food and drug grade powder falling on the inclined surface 2111c can be vibrated to fall into the vibration conveying passage 2112, thereby improving the utilization rate of the food and drug grade powder and reducing the residue of the food and drug grade powder in the inner bag of the package.

[0095] In one embodiment, the side wall of the tail end of the vibration blanking passage 2111 is formed with a narrowed collection opening, which communicates with the collection box 23 to realize the recycling of the blank inner bag. In addition, the use of the narrowed collection opening is beneficial to extending the vibration time of the blank inner bag at the closed end 2111b to realize the extension of the vibration time of the blank inner bag at the tail end of the vibration blanking passage 2111, thereby reducing the residue of the food and drug grade powder in the inner bag of the package.

[0096] As shown in Figure 5 and Figure 6 one embodiment, the width of the narrowed collection opening gradually increases from the end close to the collection box 23 to the end away from the collection box 23, which ensures that the side wall of the narrowed collection opening can block the blank inner bag to some extent, effectively extending the vibration time of the blank inner bag at the closed end 2111b.

[0097] It can be understood that although the added narrowed collection opening is beneficial to extending the vibration time of the blank inner bag at the closed end 2111b, it is not conducive to the blank inner bag falling into the collection box 23. Therefore, in one embodiment, the vibration bag breaking device 20 further comprises a tail gas cover 25, which is arranged above the bag breaking and vibration feeding area 211, and which further communicates with the collection box 23. The added tail gas cover 25 can effectively suck away the blank inner bag of the narrowed collection opening, and at the same time, the tail gas cover 25 can also effectively suck away the food and drug grade powder floating above the bag breaking and vibration feeding area 211, thereby ensuring the working environment of the bag breaking and vibration feeding area 211 and effectively avoiding the floating of too much food and drug grade powder in the working environment of the bag breaking and vibration feeding area 211, which affects the health of the workers.

[0098] It can be understood that if the tail gas outlet is arranged above the collecting box 23, and the tail gas outlet is arranged opposite to the narrowed collecting port, when the tail gas cover 25 works, the food and drug grade powder falling on the inclined surface 2111c is easily sucked away, thereby affecting the utilization rate of the food and drug grade powder. Therefore, in one embodiment, the tail gas outlet is arranged at the bottom of the end of the collecting box 23 away from the narrowed collecting port, and the tail gas outlet is communicated with the feeding pipe of the tail gas cover 25, so that a height difference is formed between the narrowed collecting port and the tail gas outlet, which is beneficial to form a detour between the narrowed collecting port and the tail gas outlet, and effectively reduces the probability of the food and drug grade powder on the inclined surface 2111c being sucked away by the tail gas cover 25.

[0099] In one embodiment, the collecting box 23 is formed with an extended narrowed flat pipe towards the end of the narrowed collecting port, and the width of the extended narrowed flat pipe gradually increases from the end close to the narrowed collecting port to the end away from the narrowed collecting port. In this way, the added extended narrowed flat pipe can prolong the horizontal length of the detour, so as to ensure that the formed detour has a right-angled bend, effectively reducing the amount of air actually reaching the narrowed collecting port, further reducing the probability of the food and drug grade powder on the inclined surface 2111c being sucked away by the tail gas cover 25, thereby better improving the utilization rate of the food and drug grade powder.

[0100] In one embodiment, the vibration bag breaking device 20 further comprises a plurality of vibration motors 26 arranged on the outer peripheral wall of the rack 21, so as to ensure that the plurality of vibration motors 26 can realize vibration of the rack 21, thereby ensuring that the food and drug grade bagged powder can complete the vibration and discharging operation in the bag breaking and vibration feeding area 211.

[0101] ​The present disclosure also provides a food and drug material processing system comprising the food and drug grade bagged powder unpacking and discharging method of any of the above embodiments. It can be understood that in the food and drug material processing system, a food and drug factory usually produces multiple different types of food and drugs at the same time. Since the formulations of each different food and drug are different, this will result in more complex types of food and drug grade bagged powder in the dedusting room. In addition, the food and drug grade bagged powder after removing the outer packaging is basically the same color, which further increases the error rate of the automatic feeding device. Therefore, the food and drug grade bagged powder unpacking and discharging method of the present disclosure applied in the food and drug material processing system not only effectively reduces the probability of feeding the wrong material, but also effectively ensures that the single dedusting efficiency of the dedusting vehicle does not decrease, and the feeding operation is relatively simple; it also avoids the problem of impurities or empty inner packaging bags falling during the discharging process of the food and drug grade powder, thereby effectively ensuring the quality of the food and drug grade powder discharging, reducing the phenomenon of food and drug grade powder remaining in the packaging inner bag, and improving the utilization rate of the food and drug grade powder. It is especially suitable for application in the food and drug material processing system of food and drug grade powder with complex types, not completely filled, and the same color of the packaging inner bag.

[0102] Compared with the prior art, the present disclosure has at least the following advantages:

[0103] 1) Since the outer packaging of each food and drug grade bagged powder is removed, the packaging inner bag and the ribbon of the food and drug grade bagged powder are exposed. At the same time, the food and drug grade bagged powder is placed vertically on the dedusting vehicle, which makes the ribbon of each food and drug grade bagged powder exposed, which is beneficial for subsequent photographing and identification to accurately obtain the feeding information of each food and drug grade bagged powder. In this way, there is no need to put the food and drug grade bagged powder down and flatten it, which not only simplifies the feeding operation, but also ensures that the single dedusting efficiency of the dedusting vehicle does not decrease; it also maximizes the dedusting blind area of each food and drug grade bagged powder.

[0104] 2) Since different types of food and drug grade bagged powder use different colored ribbons to tighten and fix the packaging inner bag, and the color of the ribbon of the same type of food and drug grade bagged powder is the same; different types of food and drug grade bagged powder can obtain different feeding information, while the same type of food and drug grade bagged powder can obtain the same feeding information, to ensure that the feeding device performs the feeding operation according to the feeding information, thereby ensuring that each bag of food and drug grade bagged powder can be accurately distributed to the corresponding bag breaking station, effectively avoiding the problem of feeding the wrong material caused by the same color of the packaging inner bag of the food and drug grade bagged powder after removing the outer packaging, especially suitable for application in the food and drug grade bagged powder with complex types, not completely filled, and the same color of the packaging inner bag.

[0105] The above-described embodiments are merely illustrative of several embodiments of the present disclosure, which are described in a relatively specific and detailed manner, but should not be construed as limiting the scope of the patent disclosure. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of the present disclosure, which are all within the scope of the present disclosure. Therefore, the scope of protection of the patent of the present disclosure should be subject to the appended claims.
