Description

Technical Field

[0001] The embodiments of the present invention relate to the field of food packaging, and more specifically, to a raw food combination weighting device and a food packaging system comprising the same. Background Art

[0002] As consumers' requirements for food quality and convenience increase, the market demand for efficient and precise food packaging solutions is growing. As raw ingredients such as fruits, vegetables and seafood are basic products in the food supply chain, the efficiency and accuracy of their packaging process are crucial to the operation of the entire industry. However, existing packaging technologies still have significant limitations when handling such ingredients, especially in terms of combined weight.

[0003] The combination weigher described in the Chinese invention patent document CN101175976A is a typical prior art. Although it performs well in terms of accurate combination and weight distribution, it is mainly aimed at those ingredients that are resistant to bumps or non-ingredients. For raw ingredients that are easily damaged and afraid of bumps, the existing combination weigher is not suitable because these ingredients also need to be placed in a material tray to avoid damage during the packaging process, especially in the combination and weight distribution link.

[0004] However, due to the design limitations of existing combination scales, ingredients that are afraid of bumping cannot be weighed directly in the equipment, which results in the process having to use manual weighing. That is, the operator needs to place a certain amount of ingredients on the electronic scale, and adjust the total weight by repeatedly adding, subtracting and replacing ingredients until it meets the predetermined total weight range. This method is not only inefficient and labor-intensive, but also difficult to adapt to large-scale, high-efficiency food packaging needs. In addition, the manual weighing process is also easily affected by human factors, such as operator fatigue, lack of experience or lack of concentration, which may lead to a decrease in weighting accuracy and affect the consistency of food packaging and overall production capacity. Summary of the invention

[0005] In order to solve one or more of the technical problems mentioned above, the present invention provides a raw food combination weighting device and a food packaging system comprising the same, wherein the raw food combination weighting device should be able to adapt to a variety of ingredients including raw ingredients that are afraid of bumps, and achieve high-efficiency and high-precision combination weighting, meet the needs of large-scale, high-efficiency and high-quality food packaging, and help improve the consistency and overall production capacity of food packaging.

Wherein, the processing module is configured to: based on the basic information of the conveyed objects obtained with the goal of meeting the predetermined weight balancing index, select multiple conveyed objects as the selected combination from the conveyed objects gathered in the preset range of the waiting conveyor, then control the material transfer component to transfer all the conveyed objects in the selected combination from the waiting conveyor to the collecting conveyor, and finally let the collecting conveyor output the selected combination, wherein the preset range is the maximum range within which the material transfer group can successfully push the conveyed objects on the waiting conveyor, and the weight balancing index is that the total weight of each raw food ingredient in the selected combination falls within the predetermined total weight range; and / or, based on the basic information of the conveyed objects obtained with the goal of meeting the predetermined weight balancing index, select multiple conveyed objects as the selected combination from the conveyed objects gathered in the preset range of the waiting conveyor The conveyor selects a plurality of conveyed objects from the conveyed objects within the preset range of the material-waiting conveyor and the conveyed objects to be gathered within the preset range of the material-waiting conveyor as a selected combination, and then controls the material-supporting transfer component to first transfer the conveyed objects within the selected combination and gathered within the preset range of the material-waiting conveyor from the material-waiting conveyor to the collecting conveyor, and then transfers the conveyed objects within the selected combination and subsequently gathered within the preset range of the material-waiting conveyor from the material-waiting conveyor to the collecting conveyor, and finally enables the collecting conveyor to output the selected combination, wherein the preset range is the maximum range in which the material-supporting transfer group can successfully push the conveyed objects on the material-waiting conveyor, and the weight index is that the total weight of each raw food ingredient in the selected combination falls within the predetermined total weight range.

[0007] According to the second aspect of the present invention, there is provided a food packaging system, comprising: a material tray conveying bus, which has a loading area, a detection area and a transfer area arranged in sequence and is used to convey the material tray to enter the loading area, the detection area and the transfer area in sequence, wherein the material tray is loaded with raw food when entering the loading area; an identification and detection device, which is arranged in the detection area of ​​the material tray conveying bus and is electrically connected to the processing module, so as to identify the identification information of the material tray and measure the quality information of the raw food carried by it; and a raw food combination weighing device as described in the first aspect of the present invention, wherein the material waiting conveyor of the raw food combination weighing device is configured to receive the material tray and the raw food loaded therein from the transfer area of ​​the material tray conveying bus.

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0019] Embodiment 1

[0020] Figure 1 The schematic diagram of the structure of the raw food combination weighting device of the first embodiment of the present invention is shown. Figure 1As shown, the first embodiment of the present invention provides a raw food combination weighting device 3, which can replace at least part of the manual work to achieve high-efficiency and high-precision combination weighting of raw food, that is, repeatedly obtain raw food groups falling within a predetermined total weight range. The raw food combination weighting device 3 can be used alone, or as a food packaging system 100 (see Figure 4 ) components to help them complete the food packaging.

[0021] like Figure 1 As shown, the raw food combination weighting device 3 includes a feed conveyor 31, which is used to gather the objects 200 to be conveyed and arrange them linearly. The objects 200 to be conveyed include a tray and raw food loaded therein, such as fruits, vegetables, seafood, etc. In an exemplary scenario, the input end of the feed conveyor 31 is set in the transfer area 13 of the tray conveyor bus 1 of the food packaging system 100, so that the food packaging system 100 can repeatedly provide the feed conveyor 31 with the same food grade. As an example, Figure 1 and Figure 2 As shown, the feed conveyor 31 includes a conveyor body 311 and a blocking mechanism 312 disposed at the output end of the conveyor body 311 and used to selectively intercept the material tray and the raw food carried by it. Among them, the conveyor body 311 can be selected as a conveying device including a belt conveyor or a roller conveyor suitable for outputting the material tray containing raw food. The blocking mechanism 312 can be selected as a fixed blocking structure or a movable blocking structure that can selectively intercept or release the material tray and the raw food carried by it. For example, the movable blocking structure can be selected as a rotating baffle driven by a power source such as a cylinder or a control motor and rotatably disposed on the conveyor body 311. During use, when the rotating baffle is driven to be perpendicular to the conveying direction of the feed conveyor 31, the blocking mechanism 312 is in a blocking state, and the rotating baffle can intercept the conveyed object 200 to achieve the assembly of the conveyed object 200 and arrange it linearly. When the rotating baffle is driven to a position parallel to the conveying direction of the material-waiting conveyor 31 , the blocking mechanism 312 is in a released state, and the conveyed object 200 can be directly conveyed by the material-waiting conveyor 31 .

[0022] The raw food combination weighting device 3 also includes a collecting conveyor 32, which is arranged on one side of the feeding conveyor 31 and is used to receive and send out the objects 200 from the feeding conveyor 31. Specifically, the collecting conveyor 32 is used to repeatedly receive the raw food group falling within a predetermined total weight range and the trays carrying each raw food in the group, and output them for subsequent processing and packaging operations. The collecting conveyor 32 can also be a conveying device such as a belt conveyor or a roller conveyor suitable for conveying the trays containing raw food.

[0023] The raw food combination weighting device 3 also includes a material transfer assembly 34 disposed on the other side of the feed conveyor 31. In terms of specific implementation, the material transfer assembly 34 can be any device that can selectively transfer each material tray containing raw food on the feed conveyor 31 to the collecting conveyor 32.

[0024] The raw food combination weighting device 3 also includes a processing module electrically connected to the material transfer assembly 34, the material waiting conveyor 31 and the collecting conveyor 32. In terms of specific implementation methods, the aforementioned processing module of this embodiment can be implemented in various suitable ways. For example, the processing module can be implemented by a general-purpose processor ("CPU") or a dedicated processor, or a combination of the two. In some scenarios, the processing module of this embodiment can also be implemented by a programmable logic controller (Programmable Logic Controller, "PLC"). Therefore, this embodiment does not impose any restrictions on the specific implementation method of the processing module, and those skilled in the art can implement it in a reasonable manner as needed based on the teachings of the present invention, and these methods still fall within the scope of protection of the present invention.

[0025] The processing module includes a first control mode and / or a second control mode. The processing module is configured to generate the following control when implementing the first control mode: based on the basic information of the conveyed object 200 obtained, with the goal of meeting the predetermined weight index, multiple conveyed objects 200 are selected from the conveyed objects 200 gathered in the preset range of the feed conveyor 31 as the selected combination, and then the material transfer component 34 is controlled to transfer all the conveyed objects 200 in the selected combination from the feed conveyor 31 to the collecting conveyor 32, and finally the collecting conveyor 32 outputs the selected combination. Among them, the preset range is the maximum range within which the material transfer component 34 can successfully push the conveyed object 200 on the feed conveyor 31, and the weight index is that the total weight of each raw food ingredient in the selected combination falls within the predetermined total weight range.

[0026] In the first control mode, the combination operation performed by the processing module when obtaining the selected combination satisfies the following relationship:

[0027]

[0028] M=M(1)

[0029] Wherein: f(1) is the valid number of combinations of the selected combination obtained after executing one selection, wherein the valid number of combinations refers to the sum of possible combinations of the selected combination; N(1) is the selection range of the number of delivered objects 200 when the delivered objects 200 are selected for the first time, which is also the maximum number of delivered objects 200 that can be assembled within the preset range; M(1) is the selected number of delivered objects 200 when the delivered objects 200 are selected for the first time, M(1)≤N(1); M is the total number of raw ingredients in the selected combination.

[0030] In the first control mode, the processing module selects M(1) objects 200 from N(1) objects 200 as the selected combination in order to meet the predetermined weight index. Then, the material transfer component 34 is controlled to transfer the selected M(1) objects 200 from the feed conveyor 31 to the collecting conveyor 32, and finally the collecting conveyor 32 outputs the selected M(1) objects. This process has the advantage of rapid response, and can efficiently select and output the selected combination, that is, the raw food group that falls within the total weight range.

[0031] In a specific application scenario, when N(1) is 5 and M(1) is 3, When the raw food in the conveyed object 200 is Hami melon and the weight index is 5±0.1kg, the conveyed objects 200 gathered in the preset range of the waiting material conveyor 31 include a tray numbered 1 and loaded with Hami melons with a weight W(1) of 1.5kg, a tray numbered 2 and loaded with Hami melons with a weight W(2) of 1.5kg, a tray numbered 3 and loaded with Hami melons with a weight W(3) of 1.8kg, a tray numbered 4 and loaded with Hami melons with a weight W(4) of 1.5kg, and a tray numbered 5 and loaded with Hami melons with a weight W(5) of 2.0kg. At this time, the combined operation of the processing module is performed. The weights are summed and a selected combination that meets the predetermined weight index (such as 5±0.1kg) is selected. This combination operation includes the following calculations:

[0032] The first time, W(1)+W(2)+W(3)=1.5kg+1.5kg+1.8kg=4.8kg ......

[0034] The third time, W(1)+W(2)+W(5)=1.5kg+1.5kg+2.0kg=5.0kg ......

[0036] The 10th time, W(3)+W(4)+W(5)=1.8kg+1.5kg+2.0kg=5.3kg

[0037] By comparison, the third calculation result satisfies the weight index, or satisfies the weight index and is closest to the ideal value of the weight index (such as 5kg), so it is selected as the selected combination, which is: the tray numbered 1 and loaded with Hami melons with a weight W(1) of 1.5kg, the tray numbered 2 and loaded with Hami melons with a weight W(2) of 1.5kg, and the tray numbered 5 and loaded with Hami melons with a weight W(5) of 2.0kg. Then, the tray transfer component 34 is controlled to transfer the trays numbered 1, 2 and 5 and loaded with the corresponding Hami melons from the waiting conveyor 31 to the collecting conveyor 32, and finally the collecting conveyor 32 outputs the trays numbered 1, 2 and 5 and loaded with the corresponding Hami melons.

[0038] The processing module is configured to generate the following control when implementing the second control mode: based on the basic information of the conveyed object 200 obtained, with the goal of meeting the predetermined weight index, multiple conveyed objects 200 are selected as the selected combination from the conveyed objects 200 gathered in the preset range of the waiting material conveyor 31 and the conveyed objects 200 that will be gathered in the preset range of the waiting material conveyor 31, and then the supporting material transfer component 34 is controlled to first transfer the conveyed objects 200 in the selected combination and already gathered in the preset range of the waiting material conveyor 31 from the waiting material conveyor 31 to the collecting conveyor 32, and then transfer the conveyed objects 200 in the selected combination and subsequently gathered in the preset range of the waiting material conveyor 31 from the waiting material conveyor 31 to the collecting conveyor 32, and finally the collecting conveyor 32 outputs the selected combination. Among them, the preset range is the maximum range in which the supporting material transfer component 34 can successfully push the conveyed objects 200 on the waiting material conveyor, and the weight index is that the total weight of each raw food in the selected combination falls within the predetermined total weight range.

[0039] In the second control mode, the combination operation performed by the processing module when obtaining the selected combination satisfies the following relationship:

[0040]

[0041]

[0042] Wherein: f(i) is the number of valid combinations of the selected combination obtained after executing the i-th selection, where i∈[2,K], and the number of valid combinations refers to the sum of possible combinations of the selected combination; N(1) is the selection range of the number of delivered objects 200 when the delivered object 200 is selected for the first time, and is also the maximum number of delivered objects 200 that can be assembled within the preset range; M(1) is the selected number of delivered objects 200 when the delivered object 200 is selected for the first time, and M(1)≤N(1); N(i) is the selection range of the number of delivered objects 200 when the delivered object 200 is selected for the i-th time, and N(i)=M(i-1); M(i) is the selected number of delivered objects 200 when the delivered object 200 is selected for the i-th time, and M(i)≤M(i-1); K is a set value, and K∈[2,M]; M is the total number of each raw food ingredient in the selected combination.

[0043] In the second control mode, the processing module first selects M(1) objects 200 from N(1) objects 200, and once or multiple times selects M(i) objects 200 from N(i), and uses all the selected objects 200 as the selected combination, and then controls the material transfer component 34 to transfer all the selected objects 200 from the waiting conveyor 31 to the collecting conveyor 32 by multiple transfers, and finally makes the collecting conveyor 32 output all the selected objects 200. The combination operation of the processing module in implementing the second control mode is similar to the combination operation when executing the first control mode. The difference mainly lies in the different amount of calculation. In order to save space, please refer to the specific application scenarios described above. Compared with the first control mode, this process has a higher number of combinations and a higher combination weight accuracy, and it is easy to select a raw food group that is closer to the ideal value (5kg) in the weight index (such as 5±0.1kg). In addition, the first control mode is only applicable to the case of M≤N(1), and the second control mode is not only applicable to the case of M≤N(1) but also to the case of M>N(1). This can greatly expand the scope of use of the original food combination weighing device 3. For example, its combination weighing capacity can be increased from selecting 2-5 Hami melons each time to selecting 2-12 Hami melons each time, and the combination weighting of more fruits such as Hami melon, pineapple, autumn pear, durian and watermelon (also applicable to vegetables or seafood, etc.) can be taken into account, which can effectively improve customers' purchasing intention, satisfaction and usage experience.

[0044] It should be noted that, when the processing module includes a first control mode and a second control mode, the start condition of the second control mode may be selected as follows: when M>N(1); the processing module is unable to select multiple conveyed objects 200 as selected combinations from the conveyed objects 200 gathered within a preset range of the waiting conveyor 31 based on the basic information of the conveyed objects 200 obtained with the goal of meeting the predetermined weight balancing index, that is, all selected combinations selected from the N(1) conveyed objects 200 in the first control mode do not meet the predetermined weight balancing index; and / or, the optimal selected combination selected in the first control mode is not as good as the optimal combination selected in the second control mode in meeting the predetermined weight balancing index.

[0045] In summary, the raw food combination weighting device 3 can control the cooperation between the material support transfer component 34, the material waiting conveyor 31 and the collecting conveyor 32 through the processing module, and at least replace part of the manual labor to achieve high-efficiency and high-precision combination weighting of raw food. At the same time, the raw food combination weighting device 3 also keeps the raw food in the material support during the implementation of the combination weighting process, effectively protecting the raw food from the risk of collision in the process. Therefore, the raw food combination weighting device 3 should be able to adapt to a variety of ingredients, including raw ingredients that are afraid of collision, and achieve its high-efficiency and high-precision combination weighting, meet the large-scale, high-efficiency and high-quality food packaging needs, and help improve the consistency and overall production capacity of food packaging.

[0046] In this embodiment, the raw food combination weighting device 3 may also include a buffer conveyor 33 for receiving the delivered object 200 and intermittently delivering it to the waiting material conveyor 31. During use, when the supporting material transfer component 34 selects and pushes the delivered object 200 on the waiting material conveyor 31, the waiting material conveyor 31 may be in a stopped state and is not suitable for continuing to receive the delivered object 200, but the buffer conveyor 33 can continue to receive the delivered object 200, thereby effectively avoiding the suspension of upstream operations such as grade sorting, and quickly replenishing the delivered object 200 to the waiting material conveyor 31 after each combined weighting operation is completed, promoting the supporting material transfer component 34 to select and push the delivered object 200 on the waiting material conveyor 31 earlier, thereby improving the overall work efficiency. That is to say, when the raw food combination weighting device 3 includes a buffer conveyor 33, the raw food combination weighting device 3 can achieve more efficient combined weighting, and is conducive to further improving the overall production capacity of food packaging.

[0047] As an example, the buffer conveyor 33 includes a conveyor body and a blocking mechanism disposed at the output end of the conveyor body and used to select interception or release of the tray and the raw food material carried by the tray, and the specific structure of the waiting material conveyor 31 can be referred to. Specifically, the conveyor body can be selected as a conveying device including a belt conveyor or a roller conveyor suitable for outputting the tray containing the raw food material. The blocking mechanism can be selected as a rotating baffle driven by a power source such as a cylinder or a control motor and rotatably disposed on the conveyor body. During use, when the rotating baffle is driven to a position perpendicular to the conveying direction of the buffer conveyor 33, the blocking mechanism is in a blocking state, and the rotating baffle can intercept the conveyed object 200 to prevent it from continuing to flow into the waiting material conveyor 31. When the rotating baffle is driven to a position parallel to the conveying direction of the buffer conveyor 33, the blocking mechanism is in a released state, and the conveyed object 200 can be directly sent to the waiting material conveyor 31 by the buffer conveyor 33.

[0048] Next, combine Figure 1 and Figure 2 The support material transfer assembly 34 is described. Figure 1 and Figure 2 In the illustrated embodiment, the material transfer assembly 34 includes a plurality of first push modules 341 sequentially arranged along the conveying direction of the feed conveyor 31. Specifically, each first push module 341 is controlled by a processing module and is used to push the object 200 from the feed conveyor 31 to the collecting conveyor 32, and the plurality of first push modules 341 are arranged in the opposite direction of the conveying direction of the feed conveyor 31 and start from the location of the blocking mechanism 312 of the feed conveyor 31 (i.e., the starting position where the object 200 begins to gather on the feed conveyor 31). At the same time, in the conveying direction of the feed conveyor 31, the center distance between adjacent first push modules 341 is equal to the shortest center distance between adjacent material trays on the feed conveyor 31. It should be noted that the shortest center distance between adjacent material trays on the feed conveyor 31 should be understood as the center distance between adjacent material trays on the feed conveyor 31 when they are in contact with each other. For example, when the cross section of the outer contour of the tray in the horizontal direction is a circle, the shortest center distance between adjacent trays on the conveyor is equal to the sum of the radii of the two circles. For another example, when the cross section of the outer contour of the tray in the horizontal direction is a square, the shortest center distance between adjacent trays on the feed conveyor 31 is equal to the sum of the radii of the inscribed circles of the two squares. In this way, each object 200 assembled on the feed conveyor 31 can be locked in a physical position by a corresponding first pushing module 341, ensuring that each first pushing module 341 can push the relative object 200 and make it enter the collecting conveyor 32.

[0049] As an alternative embodiment, the support transfer assembly 34 can be selected as a non Figure 1 and Figure 2The corresponding structure shown in the figure includes a linear slide fixedly arranged relative to the waiting material conveyor 31 and electrically connected to the processing module, and at least one first push module 341 fixedly arranged on the linear slide. The linear slide can be selected as a screw-type electric linear slide mainly composed of a control motor (such as a servo motor or a stepping motor), a screw assembly and a slide rail assembly, or a belt-type electric linear slide mainly composed of a control motor, a synchronous belt assembly and a slide rail assembly. When in use, the linear slide is controlled by the processing module and used to drive each first push module 341 to perform linear reciprocating motion along the conveying direction of the conveyor, so that each first push module 341 can also be controlled by the processing module and used to push the object 200 to be sent from the waiting material conveyor 31 to the collecting conveyor 32. In this way, each object 200 assembled on the waiting material conveyor 31 can be locked in a physical position by at least one first push module 341, ensuring that at least one first push module 341 can choose to push any object 200 passing through and make it enter the collecting conveyor 32.

[0050] In the two types of material transfer assemblies 34 mentioned above, the first push module 341 includes a linear driver 3411 fixedly arranged on one side of the material conveyor 31 or arranged on the linear slide, and a pushing member 3412 arranged on the linear driver 3411 and driven by the linear driver 3411 to move forward and backward. Among them, the linear driver 3411 can be selected as a device that can output linear motion, such as a cylinder, an electric cylinder or a hydraulic cylinder, and the pushing member 3412 can be selected as a structure of a straight line, a square or an H-shaped structure suitable for pushing the object 200. During use, when the linear driver 3411 drives the pushing member 3412 to move forward, the pushing member 3412 can push the object 200 away from the material conveyor 31; and when the linear driver 3411 drives the pushing member 3412 to move backward, the pushing member 3412 can return to the initial position when the object 200 is not pushed, so as to prepare for the next object 200 to be pushed away.

[0051] In this embodiment, the raw food combination weighting device 3 may also include a plurality of movable guardrail components 35 arranged on one side of the feed conveyor 31 close to the collecting conveyor 32 and arranged in sequence along the conveying direction of the feed conveyor 31, see Figure 2The processing module is electrically connected to each movable guardrail assembly 35, and is configured to be applicable to the object 200 to be pushed to select the corresponding movable guardrail assembly 35 as the avoidance target, and to convert it from the blocking state of preventing the object 200 from falling off from the side of the feed conveyor 31 to the release state, so as to ensure that the material transfer assembly 34 can smoothly transfer the object 200 from the feed conveyor 31 to the collecting conveyor 32. Under the control of the processing module, the movable guardrail assembly 35 can not only prevent the object 200 from falling from the side of the feed conveyor 31 away from the material transfer assembly 34 when the material transfer assembly 34 does not push the object 200, but also avoid it by switching the state when the material transfer assembly 34 pushes the object 200, so as to ensure that each selected object 200 can be smoothly pushed away from the feed conveyor 31, and at the same time, it can prevent the unselected object 200 from leaving the feed conveyor 31 together with the selected object 200.

[0052] As an example, Figure 2 As shown, the movable guardrail assembly 35 includes a first driver 351 fixed relative to the material conveyor 31 and electrically connected to the processing module, and a guardrail body 352 arranged on the side of the material conveyor 31 and capable of being driven and raised by the first driver 351. The specific structure of the guardrail body 352 can be a fence structure, a plate structure or a structure similar to an angle steel. The first driver 351 can be a device that can output linear motion, such as a cylinder, an electric cylinder or a hydraulic cylinder. The first driver 351 can be fixedly arranged on the side or above the material-waiting conveyor 31. When the first driver 351 is fixedly arranged on the side of the material-waiting conveyor 31, if it drives the guardrail body 352 to rise to the highest position, the movable guardrail assembly 35 is in a blocking state, and the guardrail body 352 can prevent the conveyed object 200 from falling from the side of the material-waiting conveyor 31 away from the material-supporting transfer assembly 34. If the first driver 351 drives the guardrail body 352 to drop to the lowest position, the movable guardrail assembly 35 is in a released state, and the guardrail body 352 allows the conveyed object 200 opposite thereto to be pushed away from the material-waiting conveyor 31. When the first driver 351 is fixedly arranged above the material-waiting conveyor 31, if the first driver 351 drives the guardrail body 352 to rise to the highest position, the movable guardrail assembly 35 is in a released state, and the guardrail body 352 allows the conveyed object 200 opposite thereto to be pushed away from the material-waiting conveyor 31. If the first driver 351 drives the guardrail body 352 to descend to the lowest position, the movable guardrail assembly 35 is in a blocking state, and the guardrail body 352 can prevent the conveyed object 200 from falling from the side of the material conveyor 31 away from the material transfer assembly 34.

[0053] As another example, the movable guardrail assembly 35 may be selected as a non Figure 1 and Figure 2The corresponding structure shown includes a second driver fixedly arranged relative to the material-waiting conveyor 31 and connected to the processing module, and a guardrail body rotatably arranged on the side of the material-waiting conveyor 31 and driven to rotate by the second driver. Among them, the specific structure of the guardrail body can be a fence structure, a plate structure or a bent plate structure with a cross-section similar to a vertical fold (ㄣ) stroke. The second driver can be selected as a linear drive device including a cylinder, an electric cylinder or a hydraulic cylinder, or it can be selected as a rotation drive device that can directly output rotation and drive the guardrail body and its rotating shaft to rotate. It should be noted that when the second driver is selected as a linear drive device, it needs to be connected to the rotating shaft of the guardrail body through a swing arm structure, so that the linear drive mechanism can drive the guardrail body to reciprocate within a certain range through the swing arm. When in use, when the second driver drives the guardrail body to rotate so that its highest point is higher than the conveying surface of the waiting conveyor 31, the movable guardrail assembly 35 is in a blocking state, and the guardrail body can prevent the conveyed object 200 from falling from the side of the waiting conveyor 31 away from the material transfer assembly 34, and when the second driver drives the guardrail body to rotate so that its highest point is lower than the conveying surface of the waiting conveyor 31, the movable guardrail assembly 35 is in a released state, and the guardrail body allows the conveyed object 200 opposite to it to be pushed away from the waiting conveyor 31.

[0054] Preferably, in the two examples of the movable guardrail assembly 35 mentioned above, the plurality of guardrail bodies 352 can be configured to be arranged in the reverse direction of the conveying direction of the feed conveyor 31 and start from the position of the blocking mechanism 312 on the feed conveyor 31, and in the conveying direction of the feed conveyor 31, the center distance between adjacent guardrail bodies 352 is equal to the shortest center distance between adjacent trays on the feed conveyor 31. In this way, each tray filled with raw food assembled on the feed conveyor 31 can be blocked or released by a corresponding guardrail body 352. When the selected object 200 is pushed away from the material-waiting conveyor 31 by the material transfer assembly 34, the guardrail body 352 opposite to the selected object 200 needs to be lowered or rotated to a position that does not block the object 200 from leaving the material-waiting conveyor 31. At the same time, the guardrail body 352 opposite to the unselected object 200 needs to be maintained at a position that prevents the object 200 from leaving the material-waiting conveyor 31. This can effectively prevent the unselected object 200 from leaving the material-waiting conveyor 31 along with the selected object 200, thereby ensuring the normal progress of the material transfer operation.

[0055] More preferably, the spacing between the guardrail body 352 and the material transfer assembly 34 in the vertical direction of the conveying direction of the feed conveyor 31 is approximately equal to the maximum size of the material tray in this direction. In this way, the material tray containing raw food can be conveyed more smoothly by the feed conveyor 31, and the material tray containing raw food can be pushed away from the feed conveyor 31 more accurately by the material transfer assembly 34. More importantly, when the material trays containing raw food are assembled and arranged in a linear array on the feed conveyor 31, the above-mentioned limitation helps each material tray to be accurately aligned with each guardrail body 352 one by one, thereby ensuring that the guardrail body 352 can better cooperate with the material transfer assembly 34, so that the material transfer assembly 34 can push the conveyed object 200 away from the feed conveyor 31 more accurately.

[0056] Embodiment 2

[0057] Embodiment 2 of the present invention provides another raw food combination weighting device 3. Figure 3 The figure shows the raw food combination weighting device 3 of the second embodiment of the present invention. Figure 1 and Figure 3 As shown, the difference between the second embodiment and the first embodiment is mainly the number of the material transfer assembly 34 and the material conveyor 31. In order to save space, the similarities between the first embodiment and the second embodiment are not repeated. Next, the differences between the two embodiments are described in detail.

[0058] In the second embodiment, the number of the supporting transfer components 34 and the material-waiting conveyors 31 is two, and the two material-waiting conveyors 31 are respectively arranged on both sides of the collecting conveyor 32. Among them, one supporting transfer component 34 is arranged on the side of one material-waiting conveyor 31 away from the collecting conveyor 32 and is used to transfer the conveyed object 200 from the material-waiting conveyor 31 to the collecting conveyor 32; and the other supporting transfer component 34 is arranged on the side of another material-waiting conveyor 31 away from the collecting conveyor 32 and is also used to transfer the conveyed object 200 from the material-waiting conveyor 31 to the collecting conveyor 32. The processing module is configured to control the two supporting transfer components 34, the two material-waiting conveyors 31 and the collecting conveyor 32 to cooperate with each other to complete the confirmation, transfer and output of the selected combination. Compared with the first embodiment, the raw food combination weighting device 3 mentioned in the second embodiment has the advantages of compact structure and higher combination weighting efficiency.

[0059] Embodiment 3

[0060] Embodiment 3 of the present invention provides a food packaging system 100 . Figure 4 The food packaging system 100 according to the third embodiment of the present invention is shown. Figure 4As shown, the food packaging system 100 includes, in addition to the raw food combination counterweight device 3 mentioned in Example 1 or Example 2, a support conveying bus 1 and an identification detection device 2. The support conveying bus 1 is composed of one or more conveyors, preferably a U-shaped structure composed of multiple conveyors, so that the material tray can circulate on it. The support conveying bus 1 has at least a loading area 11, a detection area 12 and a transfer area 13 arranged in sequence. The support conveying bus 1 is used to convey the material tray to enter the loading area 11, the detection area 12 and the transfer area 13 in sequence. When in use, it is necessary to load the raw food into the material tray when the material tray enters the loading area 11 to ensure that the material tray filled with raw food can enter the detection area 12 and the transfer area 13 in sequence. The input end of the waiting conveyor 31 of the raw food combination counterweight device 3 is arranged in the transfer area 13 of the support conveying bus 1 to ensure that the waiting conveyor 31 can be used to receive the material tray from the transfer area 13 of the support conveying bus 1 and the raw food loaded therein. The identification and detection device 2 is arranged in the detection area 12 of the material tray conveying bus 1 and is electrically connected to the processing module. The identification and detection device 2 is used to identify the identification information of the material tray and measure the quality information of the raw food materials it carries, so as to ensure that the processing module can obtain the identification information of the material tray and measure the quality information of the raw food materials it carries. In addition, the processing module can also predict the time when the material tray containing the raw food materials will reach various target positions in the future, especially the time when it reaches the buffer conveyor 33 and the waiting material conveyor 31, based on the identification and detection results (including the detection time) of the identification and detection device 2, so as to better control the raw food combination weighting device 3 to complete the confirmation, transfer and output of the selected combination.

[0061] Based on this, the food packaging system 100 can, on the one hand, realize the flow of raw food to the raw food combination and weighing device 3 through the material support conveying bus 1, avoiding the use of manual flow, and reducing labor costs and operation time; on the other hand, it can automatically obtain the basic information of the conveyed object 200 through the identification and detection device 2, that is, the identification information of the material support and the quality information of the raw food, so as to ensure that the calculation data required by the raw food combination and weighing device 3 in the process of implementing the combination and weighing have a reliable source, without the need for manual entry, thereby ensuring the accuracy of information collection and processing.

[0062] In this embodiment, the specific implementation of the identification detection device 2 includes but is not limited to the following two examples. As an example, a material tray is provided with an identification component including a QR code and storing identification information about the material tray, and the identification detection device 2 includes a weighing scale 21 (preferably a belt scale) provided in the detection area 12 of the material tray conveying bus 1 and used to obtain the weight of the raw food, and an identification module 22 provided in the detection area 12 of the material tray conveying bus 1 and used to read the identification information from the identification component. Among them. The identification component can be selected as a coating or label with a QR code, and the identification template can be selected as a camera.

[0063] As another preferred example, the tray is provided with an identification component including an electronic tag and storing identification information about the tray, and the identification detection device 2 includes a weighing scale 21 provided in the detection area 12 of the tray conveying bus 1 and used to obtain the weight of the raw food, and an identification module 22 provided in the detection area 12 of the tray conveying bus 1 and used to read the identification information from the identification component. The identification component may be an RFID tag, and the identification template may be an RFID read / write module.

[0064] In this embodiment, the number of raw food combination weighting devices 3 is preferably multiple, which are arranged at intervals in the transfer area 13 of the support conveying bus 1 and are used to process raw food of various grades. At the same time, the food packaging system 100 may also include a material sorting device 4 electrically connected to the processing module. The material sorting device 4 is arranged in the transfer area 13 of the support conveying bus 1, and is used to sort the material trays containing raw food on the support conveying bus 1 according to the grade of the raw food into the corresponding raw food combination weighting devices 3 under the control of the processing module. In this way, the food packaging system 100 not only has the function of combination weighting, but also adds the ability of grade picking, further improving the comprehensive performance and practicality of the entire system.

[0065] As an example, the material sorting device 4 includes a plurality of second pushing modules 41 arranged at intervals along the conveying direction of the material support conveying bus 1, so that a second pushing module 41 is provided in front of the input end of each raw food combination weighting device 3. Each second pushing module 41 is electrically connected to the processing module, and each second pushing module 41 is used to selectively push the material support containing raw food into the raw food combination weighting device 3 opposite thereto. The second pushing module 41 includes a linear drive, and a pushing member disposed on the linear drive and capable of being driven by the linear drive to move forward and backward. Among them, the linear drive can be selected as a device including a cylinder, an electric cylinder or a hydraulic cylinder that can output linear motion, and the pushing member can be selected as a straight-line or C-shaped structure suitable for pushing the conveyed object 200. When the linear drive drives the pushing component to move forward, the pushing component can push the object 200 to be delivered away from the material conveying bus 1 and make it enter the waiting conveyor 31 of the raw food combination counterweight device 3; and when the linear drive drives the pushing component to move backward, the pushing component can return to the initial position when the object 200 to be delivered is not pushed, so as to prepare for the pushing operation of the next object 200 to be delivered.

[0066] In order to ensure that the material sorting device 4 can implement accurate grade sorting, the material sorting device 4 may also include an identification component (such as a camera or an RFID reading and writing module) arranged in the transfer area 13 of the material conveying bus 1 and corresponding to the raw food combination weighting device 3. Thus, the processing module can control the corresponding second pushing module 41 based on the recognition results of each recognition component to selectively push the material trays passing through and containing raw food into the raw food combination weighting device 3 corresponding thereto. In addition, the processing module can also calculate the time when each delivered object 200 reaches each raw food combination weighting device 3 based on the time when the recognition detection device 2 identifies or detects the delivered object 200, and based on this, control the corresponding second pushing module 41 to selectively push the material trays passing through and containing raw food into the raw food combination weighting device 3 corresponding thereto.

[0067] In this embodiment, if Figure 5 As shown, the food packaging system 100 may also include a passive loading platform 51 that is connected to or adjacent to the loading area 11 of the support conveyor bus 1. The passive loading platform 51 is used to temporarily store the raw material box containing the original food material, so that the operator can quickly take the original food material from the passive loading platform 51 and place it on the material tray conveyed by the support conveyor bus 1, thereby achieving the purpose of rapid loading. At the same time, the food packaging system 100 may also include a lifting conveyor 52 for transporting the raw material box containing the original food material from a low place to the passive loading platform 51. When in use, the operator can place the raw material box (such as a carton) containing the original food material at the bottom of the lifting conveyor 52, and the lifting conveyor 52 will lift the raw material box containing the original food material and send it to the passive loading platform 51, thereby achieving the purpose of reducing labor intensity and improving loading efficiency.

[0068] As an example, in order to increase the number of operators supported by the passive loading platform 51 and its ease of use, the passive loading platform 51 includes a platform frame 511 connected to a lifting conveyor 52, a plurality of passive rollers 512 rotatably arranged on the platform frame 511 and evenly arranged along the conveying direction of the support conveying bus 1 in the loading area 11, and a first inclined tray 513 arranged on the platform frame 511 and located above the support conveying bus 1, wherein the top of the first inclined tray 513 is substantially flush with the top edge of the passive roller 512, and the first inclined tray 513 is used to temporarily store the raw material box containing raw ingredients. In this way, multiple operators can freely and easily adjust the position of the raw material box containing raw ingredients on the platform frame 511, so that after finding a suitable position, the raw material box containing raw ingredients can be pulled into the first inclined tray 513, and the first inclined tray 513 can tilt to keep the raw material box containing raw ingredients, so that the operator can more easily transfer the raw ingredients to the tray.

[0069] In this embodiment, if Figure 4 and Figure 6 As shown, the food packaging system 100 may also include a plurality of material retrieving platforms 6, which are arranged at the output end of the corresponding collecting conveyor 32 and are used to receive the conveyed objects 200 output by the collecting conveyor 32. When in use, the operator can complete operations such as food transfer or packing near the retrieving platform 6. It should be noted that each retrieving platform 6 corresponds to a collecting conveyor 32 of a raw food combination weighting device 3, so any raw food combination weighting device 3 can repeatedly output raw food groups (such as the selected combination mentioned above) that meet the preset total weight range to the corresponding retrieving platform 6, and the operator here can transfer or pack the raw food groups in groups to ensure that the grade of the raw food loaded into the packaging box is consistent and the total weight falls within the preset total weight range.

[0070] As an example, the reclaiming platform 6 includes a reclaiming conveyor 61, which includes a conveying area for receiving and conveying the conveyed objects 200 from the collecting conveyor 32. The reclaiming platform 6 also includes a swing plate mechanism 62, which is arranged on the input end of the reclaiming conveyor 61 and includes multiple working states. At the same time, the reclaiming platform 6 also includes a partition assembly 63, which is arranged on the reclaiming conveyor 61 and at least divides the conveying area close to the output end of the reclaiming conveyor 61 into multiple sub-conveying areas 64. Among them, the swing plate mechanism 62, when in different working states, together with the partition assembly 63, constructs multiple conveying paths passing through different sub-conveying areas 64 on the conveying area of ​​the reclaiming conveyor 61, and forces the reclaiming conveyor 61 to output the incoming conveyed objects 200 along multiple conveying paths. Based on this, the material picking platform 6 can construct multiple conveying paths on the conveying area of ​​the material picking conveyor 61 through the swing plate mechanism 62 and the partition assembly 63, so that the material picking conveyor 61 can use multiple conveying paths to complete the reception and transportation of the conveyed objects 200 (including raw ingredients), thereby having higher work efficiency and ensuring that the operator can take away raw ingredients from more conveying paths, so as to facilitate more efficient implementation of subsequent processes.

[0071] As an example, the partition assembly 63 includes a baffle. The baffle can be selected as a slat structure, a herringbone structure or an n-type structure, etc., which is used to divide the part of the conveying area close to the output end of the material-retrieving conveyor 61 into two sub-conveyoring areas 64. At the same time, the swing plate mechanism 62 includes a swing plate rotatably arranged in the conveying area of ​​the material-retrieving conveyor 61, and a power assembly (such as a rotary cylinder or other) arranged on the material-retrieving conveyor 61 and used to drive the swing plate to rotate. Among them, the rotating shaft end of the swing plate is arranged on the material-retrieving conveyor 61 and is adjacent to the baffle. Under the driving action of the power assembly, when the swing plate rotates to point to the side of the output of the raw food combination counterweight device 3, the swing plate mechanism 62 is in the first working state, and the swing plate can guide the conveyed object 200 to move from the input end of the material-retrieving conveyor 61 to the first sub-conveyoring area 64 and enable it to move along the first conveying path. When the swing plate rotates to point to the other side of the output of the raw food combination weighting device 3, the swing plate mechanism 62 is in the second working state, and the swing plate can guide the conveyed object 200 to move from the input end of the material taking conveyor 61 to the second sub-conveying area 64 and enable it to move along the second conveying path. In this way, the operator can take away the raw food that has entered the first conveying path and the end of the second conveying path at the output end of the material taking conveyor 61, thereby effectively improving the working efficiency of the material taking conveyor 61 and the material taking efficiency of the operator.

[0072] Preferably, if Figure 4 and Figure 6 As shown, the material conveying bus 1 also has a reflow zone 14 connected to the loading area 11 and the transfer area 13. The part of the reflow zone 14 of the material conveying bus 1 is arranged to pass through each material taking platform 6 or pass near it, and is used to collect empty material trays and return them to the loading area 11 of the material conveying bus 1. Based on this, the material taking platform 6 may also include at least one return conveyor 65. The input end of the return conveyor 65 is connected to or adjacent to all the sub-conveyor zones 64 of the material taking conveyor 61, and the output end thereof is connected to or adjacent to the reflow zone 14 of the material conveying bus 1 of the food packaging system 100. When the operator takes away the raw food from the output end of the material taking conveyor 1 or the return conveyor 65, the empty material tray can be returned to the reflow zone 14 of the material conveying bus 1 by the return conveyor 65, so as to facilitate the recycling of the material tray.

[0073] In this embodiment, if Figure 4 and Figure 7 As shown, the food packaging system 100 may also include a container platform 81 and a box material input track 82 for transferring raw food from each material taking platform 6 to the container platform 81, see Figure 7. The container platform 81 is configured to be separated from the material transport bus 1 and has multiple packing areas, so that multiple operators can complete the reprocessing (such as removing the fruit stalks or putting them into net bags) and packing operations of the raw ingredients at the container platform 81. The box material input track 82 can be selected as a belt conveyor or a roller conveyor or other device suitable for conveying turnover boxes containing raw ingredients. The input end of the box material input track 82 passes over the top of each material taking platform 6, and the output end is arranged in a penetrating manner in the container platform 81 and passes through each packing area. As a result, the box material input track 82 can collect turnover boxes from multiple material taking platforms 6 and all filled with raw food groups, and transport them to the material taking platform 6 in a unified manner to ensure that multiple operators can complete the reprocessing and packing operations of the raw ingredients at the material taking platform 6.

[0074] It should be emphasized that the combination of the container platform 81 and the box material input track 82 is also one of the innovations of the embodiment of the present invention. The closest existing technologies are mostly to match an independent boxing platform at the end of the grade sorting area. Although this method can also provide operators with a better assembly environment and conditions, due to the different grades of raw ingredients and the uneven number of each grade, the work efficiency of the labor required for each independent boxing platform is different, and the final production capacity of the food packaging system 100 is affected. However, the container platform 81 used in this embodiment can collect turnover boxes from different material collection platforms 6 that are all filled with raw food groups, and allow multiple operators to complementarily complete the boxing and sealing of raw ingredients at the container platform 81, thereby improving the final production capacity of the food packaging system 100.

[0075] In this embodiment, if Figure 7As shown, the food packaging system 100 may also include a second tilted tray 91 and a third tilted tray 92. The second tilted tray 91 is fixedly arranged on the portion of the box material input track 82 at the material collection platform 6, and its top end is roughly flush with the conveying surface of the box material input track 82. The second tilted tray 91 can tilt the turnover box so that the operator can take the raw food on the material collection platform 6 and easily place it in the turnover box. When the raw food group (such as the selected combination or the selected combination) that meets the total weight requirement is fully loaded into the turnover box, the operator can also easily push the turnover box filled with raw food directly into the box material input track 82, so that the box material input track 82 can transport the turnover box containing the raw food group to the collection container platform 81. The third tilted tray 92 is fixedly arranged on the collection container platform 81 or the portion of the box material input track 82 in the collection container platform 81, and its top end is roughly flush with the conveying surface of the box material input track 82. During packing, the operator can easily pull the turnover box containing the raw food group from the box material input track 82 to the third inclined tray 92, so that he can comfortably take out each raw food in the turnover box and complete the food reprocessing and packing and sealing operations at the container platform 81.

[0076] In this embodiment, the container platform 81 includes a platform frame 811 having multiple packing areas, multiple packing decks 812 provided on the platform frame 811 and separately arranged in each packing area, and a box material delivery track 813 provided at least partially on the platform frame 811 and passing through each packing area of ​​the platform frame 811. Among them, the part of the box material input track 82 in the platform frame 811 is set to be higher than the box material delivery track 813, and the top surface of each packing deck 812 is roughly flush with the conveying surface of the box material delivery track 813. When the turnover box filled with raw ingredients is delivered to the packing area, the corresponding operator can perform a top-down handling operation that is easier than from bottom to top, and transfer the turnover box filled with raw ingredients to the packing deck 812. Then, the operator needs to complete the reprocessing such as cutting the fruit stems, bagging and labeling on the packing table 812, and pack the processed raw ingredients into the packaging box, and finally push the packaging box full of raw ingredients from the packing table 812 into the box material delivery track 813 quickly and safely, so as to ensure that the packaging box full of raw ingredients can be sent to the implementation site of the next process such as sealing or stacking by the box material delivery track 813. It should be noted that the top surface of the packing table 812 is roughly flush with the conveying surface of the box material delivery track 813, which makes it easy for the operator to quickly and safely push the packaging box full of raw ingredients from the packing table 812 into the box material delivery track 813.

[0077] To sum up, the above-mentioned food packaging system 100 and its raw food combination weighting device 3 can adapt to a variety of foods including raw foods that are afraid of bumps, and achieve high-efficiency and high-precision combination weighting, meeting the needs of large-scale, high-efficiency and high-quality food packaging, which is conducive to improving the consistency and overall production capacity of food packaging.
