Description

Technical Field

[0001] Embodiments of the present utility model relate to the field of food packaging. More specifically, the present utility model relates to a manual packaging line for raw food ingredients. Background Art

[0002] In the context of the rapid development of the global food ingredient supply chain, the packaging efficiency, cost, and quality of raw food ingredients, including fruits, vegetables, and seafood, have become key factors affecting the competitiveness of the food ingredient industry. As a major producer of raw food ingredients in the world, China has a huge annual output. However, in the processes of planting, breeding, and subsequent harvesting, processing, especially the packaging link, it still faces many challenges.

[0003] With the increasing attention of consumers to the quality and safety of food ingredients, and the continuous pursuit of efficiency and cost in the food ingredient industry, the processing methods of raw food ingredients urgently need to be improved and innovated. Currently, the traditional packaging process mainly relies on manual labor to complete many links such as feeding, sorting, weighing, fine packaging (such as attaching labels or hanging tags, and soft packaging such as putting on net sleeves, film wrapping, or paper wrapping), boxing, and handling on a table. This packaging process not only has problems such as disorderly execution, uncertain cycle, and high management difficulty due to different individual habits during implementation. These problems not only make the packaging process inefficient, costly, and have large fluctuations in production capacity, but also because each operator needs to handle all processes simultaneously, it is easy to omit steps due to negligence or make operation mistakes in some links, which directly affects the packaging quality and consistency of raw food ingredients and is difficult to meet the requirements of the modern food ingredient industry for high efficiency and high standards. Summary of the Utility Model

[0004] To solve one or more of the above-mentioned technical problems, the present utility model provides a manual packaging line for raw food ingredients, which can improve packaging efficiency, reduce packaging costs and production capacity fluctuations, and take into account the improvement of packaging quality and consistency.

[0005] According to a first aspect of the present utility model, there is provided a manual packaging line for raw food ingredients, which includes: a sorting and weighing platform for a first operator to sort and weigh raw food ingredients and load the raw food ingredients into a material box during the process of sorting; a food ingredient fine packaging platform for a second operator to perform fine packaging of raw food ingredients including attaching labels and / or soft packaging and load the raw food ingredients into a packing box during the process of fine packaging; and a box and material conveying system, which is arranged to sequentially pass through the sorting and weighing platform and the food ingredient fine packaging platform. The box and material conveying system is configured to: when receiving the material box containing raw food ingredients at the location of the sorting and weighing platform, actively or passively send it to the food ingredient fine packaging platform.

[0006] After deeply studying the traditional packaging process, the applicant carried out meticulous disassembly, integration, and sequencing on it and successfully obtained the aforementioned manual packaging line for raw ingredients. Specifically, this manual packaging line for raw ingredients cleverly realizes the phased and orderly processing of the raw ingredient packaging process through the sorting and weighing platform and the ingredient fine-packaging platform, and uses the box material conveying track to connect these platforms to achieve the efficient transfer of raw ingredients between them, ensuring that this manual packaging line for raw ingredients does not require each operator to be responsible for the entire packaging process but only needs to orderly handle a small number of processes corresponding to the platform where they are located, and jointly complete all the packaging processes of raw ingredients through the collaborative method of multiple people sharing the work. This method not only stabilizes the production rhythm, reduces the management difficulties, thereby improving the packaging efficiency and reducing the packaging cost, but also, due to reducing the number and difficulty of processes that each operator needs to be responsible for, is conducive to reducing the error rate and omission risk that occur during the operation of the operator, effectively improving the packaging quality and consistency of raw ingredients. In addition, this breakthrough is expected to promote the modern food ingredient industry to move towards a higher-quality development stage. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0016] Next, the technical solutions in the embodiments of the present disclosure will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments are some, but not all, embodiments of the present disclosure. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the present disclosure.

[0017] Figure 1 The structural schematic diagram of the manual packaging line for raw food ingredients in Embodiment 1 of the present utility model is shown; Figure 5 The structural schematic diagram of the manual packaging line for raw food ingredients in Embodiment 2 of the present utility model is shown. As Figure 1 or Figure 5 shown, both Embodiment 1 and Embodiment 2 provide a manual packaging line 100 for raw food ingredients. The manual packaging line 100 for raw food ingredients includes a sorting and weighing platform 1, a food ingredient cleaning platform 2, and a food ingredient fine-packaging platform 3, and a box material conveying system that sequentially passes through the sorting and weighing platform 1, the food ingredient cleaning platform 2, and the food ingredient fine-packaging platform 3. When in use, the first operator needs to obtain the raw material box 300 containing raw food ingredients sent by the box material conveying system (such as the box material input track 5 described below) at the sorting and weighing platform 1 and obtain raw food ingredients from it (see Figure 1 ), or directly obtain raw food ingredients from the nearby open container 500 at the sorting and weighing platform 1 (see Figure 5), and complete the sorting and weighing of raw ingredients on the sorting and weighing platform 1. For example, conduct quality screening on oranges, pears or apples on the sorting and weighing platform 1, and put the screened oranges, pears or apples into the material box 200 (including turnover box or packing box) one by one until the total weight of the evenly sized oranges, pears or apples in the material box 200 reaches 5 kg. Finally, the first operator places the material box 200 containing raw ingredients at the location of the sorting and weighing platform into the box material conveying system to ensure that the box material conveying system can actively or passively send it to the food cleaning platform 2, enabling the third operator to clean the raw ingredients on the food cleaning platform 2 (such as cutting the fruit stalks and / or removing foreign objects), and after completion of cleaning, load them back into the material box 200. Then, when the box material conveying system receives the material box 200 containing raw ingredients from the food cleaning platform 2, it is used to actively or passively send the full material box 200 to the location of the food fine packaging platform 3 in sequence, so that the second operator can obtain the material box 200 (including turnover box or packing box) containing raw ingredients sent by the box material conveying system at the food fine packaging platform 3, and conduct fine packaging including attaching labels and / or soft packaging on it at the food fine packaging platform 3. For example, conduct label attaching and soft packaging on 5 kg of oranges, pears or apples, and load them into packing boxes of the same specification (such as 5 kg) during the process of soft packaging. Then the second operator needs to place the packing box containing raw ingredients at the location of the food fine packaging platform 3 into the box material conveying system so that the box material conveying system can actively or passively send it out of the food fine packaging platform 3.

[0018] It should be noted that the label attaching mentioned above should be understood to include label pasting, label tying or label hanging, etc., whose purpose is to indicate the source of the raw ingredients and even record some necessary information (such as origin, variety, etc.). Among them, label pasting means pasting the label on the raw ingredients, label tying means tying the belt or plate with the logo to the raw ingredients, and label hanging means hanging the sign through the hanging rope on the raw ingredients; the soft packaging mentioned above should be understood to include net sleeve covering, film wrapping or paper wrapping, etc., whose purpose is to protect the raw ingredients to reduce damage to their appearance before reaching the hands of users. Among them, net sleeve covering means covering the net sleeve outside the raw ingredients, film wrapping means wrapping the film outside the raw ingredients, and paper wrapping means wrapping the paper outside the raw ingredients.

[0019] It should be noted that the food ingredient cleaning platform 2 is not an essential component of the raw food ingredient manual packaging line 100. For raw food ingredients such as oranges and bananas that have no stalks and are relatively clean, generally no cleaning or only simple cleaning is required. At this time, the raw food ingredient manual packaging line 100 may only include the sorting and weighing platform 1, the food ingredient fine packaging platform 3, and the box material conveying system that sequentially passes through the sorting and weighing platform 1 and the food ingredient fine packaging platform 3. For raw food ingredients such as apples and pears that have stalks and are easily contaminated (such as having foreign objects like insect eggs and spider webs in the fruit nests), generally more complex cleaning operations need to be carried out. At this time, the raw food ingredient manual packaging line 100 needs to include the sorting and weighing platform 1, the food ingredient cleaning platform 2, and the food ingredient fine packaging platform 3, and the box material conveying system that sequentially passes through the sorting and weighing platform 1, the food ingredient cleaning platform 2, and the food ingredient fine packaging platform 3.

[0020] After in-depth research on the traditional packaging process, the applicant carried out detailed disassembly, integration, and sequencing on it and successfully obtained the aforementioned raw food ingredient manual packaging line 100. Specifically, the raw food ingredient manual packaging line 100 cleverly realizes the phased and orderly processing of the raw food ingredient packaging process through the sorting and weighing platform 1, the food ingredient cleaning platform 2, and the food ingredient fine packaging platform 3, and uses the box material conveying track 4 to connect these platforms to achieve the efficient transfer of raw food ingredients between them, ensuring that the raw food ingredient manual packaging line 100 does not require each operator to be responsible for the entire packaging process but only needs to handle a small number of processes corresponding to the platform where they are located, and completes all the packaging processes of raw food ingredients through the collaborative method of multiple people sharing the work. This method can not only improve the packaging efficiency and reduce the packaging cost, but also, due to reducing the number and difficulty of processes that each operator needs to be responsible for, is conducive to reducing the error rate and omission risk that occur during the operation of the operator, and effectively improving the packaging quality and consistency of raw food ingredients. In addition, this breakthrough progress is expected to promote the modern food ingredient industry to move towards a higher-quality development stage.

[0021] In the first and second embodiments, as Figure 1 、 Figure 2 、 Figure 5 and Figure 6As shown in the figure, the box material conveying system includes a box material conveying track 4, which is arranged to pass through the sorting and weighing platform 1, the food material cleaning platform 2 and the food material fine packaging platform 3, and is used to convey the material box 200 containing raw food materials from the sorting and weighing platform 1 to the food material fine packaging platform 3 and pass through the food material cleaning platform 2. The box material conveying track 4 includes an idle roller track, a belt conveyor and / or a roller conveyor. Among them, the idle track needs to be pushed manually to achieve passive material conveying, while the belt conveyor and the roller conveyor can achieve active material conveying. The box material conveying system may further include a box material output track 6. The box material output track 6 includes an idle roller track, a belt conveyor and / or a roller conveyor. Part of the box material output track 6 is arranged inside the food material fine packaging platform 3, and is used to receive the packaging box containing raw food materials provided by the second operator inside the food material fine packaging platform 3 and send it out of the food material fine packaging platform 3 actively or passively. Thus, the second operator standing at the food material fine packaging platform 3 can put the full (i.e., filled with raw food materials) packaging box into the box material output track 6 after completing the fine packaging operation, and then the box material output track 6 sends it out of the food material fine packaging platform 3 actively or passively, especially to the shipping area, effectively reducing the labor intensity and acquisition time required for the second operator to move the full packaging box.

[0022] In the first embodiment, in order to further improve the packaging efficiency, the box material conveying system may further include a box material input track 5, see Figure 5 . The box material input track 5 includes an idle roller track, a belt conveyor and / or a roller conveyor. Part of the box material input track 5 is arranged inside the sorting and weighing platform 1, and is used to receive the raw material box 300 containing raw food materials and send it to the sorting and weighing platform 1 actively or passively. Thus, it is ensured that the first operator standing at the sorting and weighing platform 1 can conveniently obtain the raw material box 300 containing raw food materials and obtain the raw food materials from it, thereby effectively reducing the labor intensity and acquisition time required for the first operator to obtain the raw material box 300. In the second embodiment, the box material conveying system does not include the box material input track 5, and an open container 500 is directly arranged near the first operator and the open container 500 is used to supply raw food materials to the first operator.

[0023] Since the feeding methods adopted in the first embodiment and the second embodiment are different, resulting in different specific structures of the sorting and weighing platform 1, the two are described separately. Next, in combination with Figures 1 to 2 an exemplary description of the sorting and weighing platform 1 mentioned in the first embodiment is given. As Figure 1 and Figure 2As described above, the sorting and weighing platform 1 includes a first platform frame 11. The first platform frame 11 has a plurality of pretreatment areas 111 arranged at intervals in the horizontal direction, such that both the box material input track 5 and the box material conveying track 4 pass through each pretreatment area 111. The plurality of pretreatment areas 111 are preferably arranged in an array, especially in one row with multiple columns, so as to facilitate the box material input track 5 and the box material conveying track 4 to be smoothly arranged to pass through. The sorting and weighing platform 1 further includes a plurality of storage plates 12 having storage surfaces. The plurality of storage plates 12 are all arranged on the first platform frame 11 and are separately located in each pretreatment area 111 to ensure that at least one storage plate 12 is evenly distributed in each pretreatment area 111. The storage surface of the storage plate 12 is used to carry the raw material box 300 containing the raw ingredients. The sorting and weighing platform 1 further includes a plurality of weighing plates 13 having weighing surfaces. The plurality of weighing plates 13 are all arranged on the first platform frame 11 and are separately located in each pretreatment area 111 to ensure that at least one weighing plate 13 is evenly distributed in each pretreatment area 111. The sorting and weighing platform 1 further includes a weighing scale 14, and the weighing scale 14 is arranged on the weighing plate 13 and is carried by its weighing surface. The weighing scale 14 can weigh at least one grade of material boxes 200, and each grade of material box 200 contains raw ingredients matching its grade. The sorting and weighing platform 1 further includes a plurality of buffer plates 15 having buffer surfaces. The plurality of buffer plates 15 are all arranged on the first platform frame 11 and are separately located in each pretreatment area 111 to ensure that at least one buffer plate 15 is evenly distributed in each pretreatment area 111. The buffer surface of the buffer plate 15 is used to temporarily store the material boxes 200 and the raw ingredients loaded therein. The sorting and weighing platform 1 may further include a plurality of spare plates 17. The plurality of spare plates 17 are all arranged on the first platform frame 11 and are separately located in each pretreatment area 111 to ensure that at least one spare plate 17 is evenly distributed in each pretreatment area 111. The spare plate 17 can be selected to carry the raw material box 300 or the material box 200 according to actual needs.

[0024] In use, the box material input track 5 delivers the raw material box 300 containing raw ingredients to the pre-treatment area 111 of the sorting and weighing platform 1. In any one of the pre-treatment areas 111, the first operator standing near the pre-treatment area 111 needs to place the material box 200 of the first set level on the weighing scale 14, and then place the material box 200 of the second set level on the buffer table 15. At the same time, the first operator needs to transfer the incoming raw material box 300 containing raw ingredients from the box material input track 5 to the storage table 12, and obtain raw ingredients from this raw material box 300 and perform sorting. That is, the first operator needs to pick out the raw ingredients of the first set level (such as relatively large in volume and without defects) in the raw material box 300 and successively put them into the material box 200 of the first set level, and at the same time, alternately pick out the raw ingredients of the second set level (such as relatively small in volume and without defects) from the raw material box 300 and successively put them into the material box 200 of the second set level. When it is known through the weighing scale 14 that the material box 200 of the first set level and the raw ingredients of the first set level successively loaded therein have met the total weight index, the first operator needs to transfer the qualified and full material box 200 of the first set level to the box material conveying track 4, and the box material conveying track 4 will send it to the food cleaning platform 2. Then, transfer the material box 200 filled or half-filled with raw ingredients of the second set level to the weighing scale 14. If it is not full, successively put the raw ingredients of the second set level from the raw material box 300 into the material box 200 of the second set level until it is known through the weighing scale 14 that this material box 200 and the raw ingredients of the second set level successively loaded therein have met the total weight index. The first operator stops the transfer operation and transfers the qualified and full material box 200 of the second set level to the box material conveying track 4, and the box material conveying track 4 will actively or passively send it out of the first platform frame 11. Repeating the above process can continuously complete the sorting and weighing of raw ingredients. In addition, the sorting and weighing platform 1 can also selectively support the first operator to perform the removal operation of fruit bags or mesh sleeves here according to actual needs.

[0025] That is to say, the sorting and weighing platform 1 allows multiple first operators to perform the sorting and weighing of raw ingredients in parallel and without interference by means of zoning, and realizes the efficient and easy handling of the raw material box 300 and the material box 200 with the help of the box material input track 5 and the box material conveying track 4. Thus, it can facilitate the first operator to quickly and easily perform the sorting and weighing of raw ingredients, ensure that the sorting and weighing platform 1 can support multiple first operators to complete the sorting and weighing of raw ingredients in parallel, efficiently and without interference, and contribute to improving the overall efficiency of food packaging.

[0026] It should be noted that if, during the sorting process, it is necessary not only to load the raw food materials of the first set grade and the second set grade into the material boxes 200 of different grades, but also to load raw food materials of more grades into other grade material boxes 200, the number or area of the buffer pallets 15 can be increased in each pretreatment area 111. In addition, in addition to helping the first operator to perform sorting of two or more grades, the sorting and weighing platform 1 can also perform sorting of one grade, that is, the first operator needs to pick out the fruits and melons with qualified quality and put them into the material box 200, and then throw the fruits and melons with unqualified quality into the waste box (for example, placed on the buffer pallet 15) or keep them in the raw material box 300. In addition, the weighing scale 14 can be an optional accessory. During the sale of the manual packaging line 100 for raw food materials, the customer has the option to decide whether it includes the weighing scale 14. If the customer chooses not to purchase the weighing scale 14, it is necessary to ensure that a weighing scale 14 that can cooperate with the sorting and weighing platform 1 to implement the complete function has been prepared before using the sorting and weighing platform 1.

[0027] In order to further reduce the labor intensity of the first operator, the storage surface of the storage pallet 12 near the edge of the first platform frame 11 can be configured to be adjacent to the box material input track 5 and be substantially flush with the material-carrying conveying layer of the box material input track 5. In this way, when the box material input track 5 sends the raw material box 300 containing raw food materials into the pretreatment area 111 of the first platform frame 11, the first operator standing near the pretreatment area 111 can directly pull the full raw material box 300 from the box material input track 5 onto the storage surface of the storage pallet 12. This operation can effectively reduce the labor intensity of the first operator compared with manual handling. Similarly, the weighing surface of the weighing pallet 13 is set so that the weighing surface of the weighing scale 14 is adjacent to the box material conveying track 4 and keeps the weighing surface substantially flush with the material-carrying conveying layer of the box material conveying track 4, thereby ensuring that the first operator can directly push the qualified and full material box 200 from the weighing scale 14 into the box material conveying track 4 after weighing, and further reducing the labor intensity of the first operator. Similarly, the buffer surface of the buffer pallet 15 near the edge of the first platform frame 11 can be set to be adjacent to the weighing scale 14 and be substantially flush with the weighing surface of the weighing scale 14. Thus, the first operator can directly push the material box 200 containing raw food materials from the buffer surface into the weighing scale 14, and further reduce the labor intensity of the first operator.

[0028] Considering that the horizontal plane where the manual packaging line 100 for raw ingredients is located may not be the same as the horizontal plane where the first operator stands, the following definitions are made here. That is, the horizontal plane where the manual packaging line 100 for raw ingredients is located is defined as the first horizontal plane, and the horizontal plane where the first operator using the manual packaging line 100 for raw ingredients stands is defined as the second horizontal plane, where the second horizontal plane can be optionally coincident with the first horizontal plane or higher than the first horizontal plane. On this basis, in combination with the principle of ergonomics, the height of the part of the box material input track 5 inside the sorting and weighing platform 1 relative to the second horizontal plane is preferably 1000 mm - 1300 mm, and the height of the part of the box material conveying track 4 inside the sorting and weighing platform 1 relative to the second horizontal plane is preferably 500 mm - 800 mm. This not only directly limits the heights of the box material input track 5 and the box material conveying track 4, but also indirectly limits the heights of the buffer table board 15, the weighing scale 14, the storage table board 12, and the spare table board 17, and ensures that their heights are suitable for the first operator to easily perform the corresponding operations. In addition, the design of the storage table board 12 makes its storage table surface higher than the buffer table surface of the buffer table board 15. This feature ensures that when the first operator transfers the raw material box 300 filled with raw ingredients from the storage table board 12 to the buffer table board 15, a more convenient top-down handling operation can be implemented, which significantly improves the operation efficiency and convenience compared with the bottom-up handling.

[0029] In the first embodiment, the buffer table board 15 and the spare table board 17 can both be preferably of a table structure, that is, the buffer table surface of the buffer table board 15 and the spare table surface of the spare table board 17 are both arranged along the horizontal direction. Based on the principle of ergonomics, when the height of the buffer table board 15 relative to the second horizontal plane is 500 mm - 800 mm, its table surface is more suitable for the first operator to complete the sorting and weighing operations more efficiently and comfortably at the aforementioned height.

[0030] In the first embodiment, the storage table board 12 can be selected as a table structure, that is, its storage table surface is arranged along the horizontal direction. However, in order to facilitate the first operator to perform the material taking operation, the storage table board 12 is preferably selected as an inclined supporting structure, that is, the storage table board 12 includes an inclined support plate provided on the first platform frame 11 and having a storage table surface, and a blocking structure provided at the lower end of the inclined support plate away from the first platform frame 11 and used to prevent the raw ingredients from sliding off the storage table surface. Among them, the blocking structure can be selected as a guardrail, a baffle, or other structures suitable for implementing blocking. During use, the first operator can directly pull the raw material box 300 filled with raw ingredients onto the inclined support plate of the storage table board 12, and use the blocking structure to prevent the raw material box 300 from sliding off the inclined support plate. At the same time, the inclined support plate is also used to keep the raw material box 300 in an inclined state, so that the first operator can more conveniently and quickly take away the raw ingredients from the raw material box 300.

[0031] In the first embodiment, the sorting and weighing platform 1 may further include a first empty box supply track 16 disposed on the first platform frame 11 and passing through each pretreatment area 111. The first empty box supply track 16 may be an idle roller track or a flat plate structure. The first empty box supply track 16 is used to store the empty raw material boxes 300 and / or material boxes 200, and is set higher than the box material input track 5 and the box material conveying track 4. In use, the first operator can temporarily place the emptied raw material boxes 300 and / or unused material boxes 200 on the first empty box supply track 16 so as to complete the sorting and weighing of the raw ingredients more quickly.

[0032] In the second embodiment, the box material conveying system does not include the box material input track 5, but the raw ingredient manual packaging line 100 further includes a feeding area adjacent to the sorting and weighing platform 1. The feeding area is used to carry the open containers 500 (such as iron barrels or plastic barrels, etc.) containing the raw ingredients. Refer to Figure 5 . The first operator standing at the sorting and weighing platform 1 can conveniently obtain the raw ingredients from the open container 500, thereby effectively reducing the labor intensity and acquisition time required for the operator to obtain the raw material box 300.

[0033] As Figure 5 and Figure 6 described, the sorting and weighing platform 1 of the second embodiment includes a first platform frame 11. The first platform frame 11 has a plurality of pretreatment areas 111 arranged at intervals in the horizontal direction, such that the box material conveying track 4 passes through each pretreatment area 111. The plurality of pretreatment areas 111 are preferably arranged in an array, especially one row with multiple columns, so that the box material conveying track 4 can be set to pass through smoothly. The sorting and weighing platform 1 further includes a plurality of weighing platform plates 13 having weighing table surfaces. The plurality of weighing platform plates 13 are all disposed on the first platform frame 11 and are separately located in each pretreatment area 111 to ensure that at least one weighing platform plate 13 is evenly distributed in each pretreatment area 111. The sorting and weighing platform 1 further includes a weighing scale 14, and the weighing scale 14 is disposed on the weighing platform plate 13 and is carried by its weighing table surface. The weighing scale 14 can weigh at least one grade of material boxes 200, and each grade of material box 200 contains raw ingredients matching its grade. The sorting and weighing platform 1 further includes a plurality of buffer platform plates 15 having buffer table surfaces. The plurality of buffer platform plates 15 are all disposed on the first platform frame 11 and are separately located in each pretreatment area 111 to ensure that at least one buffer platform plate 15 is evenly distributed in each pretreatment area 111. The buffer table surface of the buffer platform plate 15 is used to temporarily store the material box 200 and the raw ingredients contained therein. The number of feeding areas is also multiple, and the multiple feeding areas are separately arranged at the locations where each pretreatment area 111 is located, and an open container 500 containing raw ingredients is placed in each feeding area.

[0034] In use, in any one of the preprocessing areas 111, the first operator standing near the preprocessing area 111 places the material box 200 of the first set level on the weighing scale 14, and then places the material box 200 of the second set level on the buffer pallet 15. At the same time, the first operator needs to obtain the raw ingredients from the nearby open container 500 and perform sorting on them. That is, the first operator needs to pick out the raw ingredients of the first set level (such as those with a relatively large volume and no defects) in the open container 500 and successively put them into the material box 200 of the first set level. At the same time, the first operator also needs to pick out the raw ingredients of the second set level (such as those with a relatively small volume and no defects) from the open container 500 in an interspersed manner and successively put them into the material box 200 of the second set level. When it is known through the weighing scale 14 that the material box 200 of the first set level and the raw ingredients of the first set level successively loaded into it have met the total weight index, the first operator needs to transfer the qualified and full material box 200 of the first set level to the box material conveying track 4, and the box material conveying track 4 will send it to the food cleaning platform 2. Then, transfer the material box 200 filled or half-filled with the raw ingredients of the second set level to the weighing scale 14. If it is not full, successively put the raw ingredients of the second set level from the raw material box 300 into the material box 200 of the second set level until it is known through the weighing scale 14 that this material box 200 and the raw ingredients of the second set level successively loaded into it have met the total weight index. The first operator stops the transfer operation and transfers the qualified and full material box 200 of the second set level to the box material conveying track 4, and the box material conveying track 4 will actively or passively send it to the food cleaning platform 2. By repeating the above process, the sorting and weighing of the raw ingredients can be continuously completed. In addition, the sorting and weighing platform 1 can also selectively support the first operator to perform the operation of removing fruit bags or mesh covers here according to actual needs.

[0035] That is to say, the sorting and weighing platform 1 used in the second embodiment also allows multiple first operators to perform the sorting and weighing of raw ingredients in parallel and without interference by dividing areas, and realizes the efficient and easy handling of the material box 200 with the help of the box material conveying track 4. Thus, it can facilitate the first operator to quickly and easily perform the sorting and weighing of raw ingredients, ensure that the sorting and weighing platform 1 can support multiple first operators to complete the sorting and weighing of raw ingredients in parallel, efficiently and without interference, and contribute to improving the overall efficiency of food packaging.

[0036] In order to further reduce the labor intensity of the first operator, the weighing surface of the weighing platform plate 13 is set such that the weighing surface of the weighing scale 14 is adjacent to the box material conveying track 4 and is kept substantially flush with the material-carrying conveying layer of the box material conveying track 4, thereby ensuring that the first operator can directly push the qualified and full material box 200 from the weighing scale 14 into the box material conveying track 4 after weighing, and further reducing the labor intensity of the first operator. Similarly, the buffer surface of the buffer platform plate 15 near the edge of the first platform frame 11 can be set to be adjacent to the weighing scale 14 and substantially flush with the weighing surface of the weighing scale 14, whereby the first operator can directly push the material box 200 containing the raw ingredients from the buffer surface into the weighing scale 14, and further reduce the labor intensity of the first operator.

[0037] Considering that the horizontal plane where the raw ingredient manual packaging line 100 is located is not necessarily the same as the horizontal plane where the first operator stands, the following definitions are made here. That is, the horizontal plane where the raw ingredient manual packaging line 100 is located is defined as the first horizontal plane, and the horizontal plane where the first operator using the raw ingredient manual packaging line 100 stands is defined as the second horizontal plane, where the second horizontal plane can be selected to coincide with the first horizontal plane or be higher than the first horizontal plane. On this basis, in combination with the principle of ergonomics, the height of the part of the box material conveying track 4 within the sorting and weighing platform 1 relative to the second horizontal plane is preferably 500 mm - 800 mm. This not only directly limits the height of the box material conveying track 4, but also indirectly limits the height of the weighing scale 14 of the buffer platform plate 15, and ensures that their heights are suitable for the first operator to easily perform the corresponding operations.

[0038] In the second embodiment, the sorting and weighing platform 1 may further include a first empty box supply track 16 provided on the first platform frame 11 and passing through each pretreatment area 111. The first empty box supply track 16 can be an idler roller track or a flat plate structure. The first empty box supply track 16 is used to store the empty material boxes 200 and is set higher than the box material conveying track 4. During use, the first operator can temporarily place the emptied raw material box 300 and / or the unused material box 200 on the first empty box supply track 16 so as to complete the sorting and weighing of the raw ingredients more quickly.

[0039] In the first and second embodiments, the manual packaging line 100 for raw food materials may further include a food material cleaning platform 2 provided between the sorting and weighing platform 1 and the food material fine packaging platform 3 and passed by the box material conveying system. During use, when the box material conveying system receives the material box 200 containing raw food materials from the sorting and weighing platform 1, it actively or passively sends the material box 200 to the location of the food material cleaning platform 2, enabling the third operator to clean the raw food materials on the food material cleaning platform 2 and then load them back into the material box 200 after completion of the cleaning. Then, when the box material conveying system receives the material box 200 containing raw food materials from the food material cleaning platform 2, it actively or passively sends the full material box 200 to the location of the food material fine packaging platform 3 in sequence, so as to facilitate the second operator to complete the fine packaging of the raw food materials on the food material fine packaging platform 3.

[0040] Based on the design principle of ergonomics, the height of the part of the box material conveying track 4 inside the food material cleaning platform 2 relative to the second horizontal plane is preferably 500 mm - 800 mm, and the cleaning tabletop of the cleaning table board 21 is horizontally arranged, whereby it can be ensured that the cleaning tabletop is more suitable for the third operator to complete the cleaning operation more efficiently and comfortably here. At the same time, the edge of the cleaning tabletop of the cleaning table board 21 close to the box material conveying track 4 can also be set to be adjacent to the box material conveying track 4 and be substantially flush with the material-carrying conveying layer of the box material conveying track 4, whereby it is not only convenient for the third operator to pull the material box 200 containing raw food materials from the box material conveying track 4 onto the cleaning table board 21, but also convenient for the third operator to push the material box 200 containing raw food materials back from the cleaning table board 21 onto the box material conveying track 4.

[0041] As an example, the food material cleaning platform 2 includes one or more cleaning table boards 21 fixed relative to the box material conveying track 4. The cleaning table board 21 can be directly fixed on the box material conveying track 4 or fixed to the ground through a bracket structure. The cleaning table board 21 includes a cleaning tabletop for carrying the material box 200 containing raw food materials and for the third operator to perform the cleaning operation. During use, when the box material conveying track 4 sends the material box 200 containing raw food materials to the food material cleaning platform 2, the third operator can transfer the material box 200 containing raw food materials onto the cleaning table board 21 and complete cleaning operations such as cutting the fruit stalks and / or removing foreign objects on the cleaning table board 21, and then transfer the material box 200 containing raw food materials back to the box material conveying track 4 so that the box material conveying track 4 conveys the raw food materials to the food material fine packaging platform 3.

[0042] As another example, the food ingredient cleaning platform includes a third platform frame and a cleaning table board with a cleaning tabletop. The third platform frame has a cleaning area, and the cleaning table board is arranged on the third platform frame and located within the cleaning area. The cleaning tabletop is used to carry the material box containing the raw food ingredients and for the third operator to perform cleaning operations. The box material conveying track includes a first sub-track arranged to pass through the sorting and weighing platform 1 and the cleaning area of the third platform frame, and a second sub-track arranged to pass through the food ingredient fine-packaging platform 3 and the cleaning area of the third platform frame, where the layout heights of the first sub-track and the second sub-track within the third platform frame are different. Both the first sub-track and the second sub-track include idle roller tracks, belt conveyors, and / or roller conveyors. During use, when the first sub-track transports the material box 200 containing the raw food ingredients from the sorting and weighing platform 1 to the food ingredient cleaning platform 2, the third operator can transfer the material box 200 containing the raw food ingredients to the cleaning table board and complete cleaning operations such as cutting the fruit stalks and / or removing foreign objects on the cleaning table board, and then transfer the material box 200 containing the raw food ingredients back to the second sub-track so that the second sub-track transports the raw food ingredients to the food ingredient fine-packaging platform 3.

[0043] Next, in combination with Figure 1 、 Figure 4 and Figure 5 an exemplary description will be given of the food ingredient fine-packaging platform 3 mentioned in Embodiment 1 and Embodiment 2. As Figure 1 、 Figure 4 and Figure 5 shown, the food ingredient fine-packaging platform 3 includes a second platform frame 31. The second platform frame 31 has a plurality of reprocessing areas 311 arranged at intervals in the horizontal direction, and both the box material conveying track 4 and the box material output track 6 of the box material conveying system pass through each reprocessing area 311. The plurality of reprocessing areas 311 are preferably arranged in an array, especially one row with multiple columns, so that the box material conveying track 4 and the box material output track 6 can pass through them. The food ingredient fine-packaging platform 3 further includes a plurality of fine-packaging table boards 32 with fine-packaging tabletops. The plurality of fine-packaging table boards 32 are all arranged on the second platform frame 31 and separately located within each reprocessing area 311, so that at least one fine-packaging table board 32 is evenly distributed within each reprocessing area 311. The fine-packaging tabletop of the fine-packaging table board 32 is used to carry the raw material box 300 containing the raw food ingredients and for the second operator to perform fine-packaging operations here.

[0044] When the material box 200 is a reusable container and the reusable container containing the raw food materials has been sent to the food material fine-packaging platform 3 by the box material conveying track 4, in any of the reprocessing areas 311, a second operator standing near the reprocessing area 311 can transfer the arrived reusable container to the fine-packaging table 32, and take out the raw food materials from the reusable container to perform fine-packaging operations such as attaching labels and / or soft packaging on the raw food materials. Then, the raw food materials are first placed into the packaging box that has been placed on the fine-packaging table 32 in advance, and then the packaging box is transferred to the box material output track 6 so that the box material output track 6 can send it out of the food material fine-packaging platform 3, especially to the shipping area. When the material box 200 is a packaging box and the packaging box containing the raw food materials has been sent to the food material fine-packaging platform 3 by the box material conveying track 4, in any of the reprocessing areas 311, a second operator standing near the reprocessing area 311 can transfer the arrived packaging box from the box material conveying track 4 to the fine-packaging table 32, and take out the raw food materials from the material box 200 to perform fine-packaging operations such as attaching labels and / or soft packaging on the raw food materials. Then, the raw food materials are all put back into the packaging box, and then the packaging box is transferred to the box material output track 6 so that the box material output track 6 can send it out of the food material fine-packaging platform 3, especially to the shipping area.

[0045] In the first and second embodiments, the sealing operation of the packaging box can be implemented at the food material fine-packaging platform 3 or on the box material output track 6. As an example, a second operator standing near any of the reprocessing areas 311 can implement the sealing operation of the packaging box at the food material fine-packaging platform 3, such as using tape to bond the docking gap of the double-page flip cover of the packaging box, or snapping the flip box cover of the packaging box onto its box body. As another example, the box material output track 6 includes a recycling section located inside the food material fine-packaging platform 3 and a sealing section 61 located outside the food material fine-packaging platform 3. One or more fourth operators standing near the sealing section 61 can implement the sealing operation at the box material output track 6. In the sealing operation, different packaging boxes will adopt different sealing operations. For example, when the packaging box is a split-type packaging box, the fourth operator needs to stand near the sealing section 61 and snap the detachable box cover onto the box body that has been filled with raw food materials. For another example, when the packaging box is an integral-type packaging box, which includes a box body and a flip cover connected thereto, the fourth operator needs to stand near the sealing section 61, flip the flip cover and cover it on the box body that has been filled with raw food materials, and use a snap structure or sealing tape to firmly paste the flip cover in the closed state on the box body.

[0046] In the first and second embodiments, the part of the box material conveying track 4 inside the food material fine-packaging platform 3 can be set higher than the part of the box material output track 6 inside the food material fine-packaging platform 3, or can be set lower than the part of the box material output track 6 inside the food material fine-packaging platform 3. As Figure 7As shown, preferably, based on the ergonomic design principle, the height of the part of the box material conveying track 4 within the food material fine packaging platform 3 relative to the second horizontal plane is 1000 mm - 1300 mm, and the height of the part of the box material output track 6 within the food material fine packaging platform 3 relative to the second horizontal plane is 500 mm - 800 mm. At the same time, the fine packaging surfaces of the fine packaging platen 32 are all arranged along the horizontal direction, and the edge of the fine packaging surface close to the second platform frame 31 is set to be adjacent to the box material output track 6 and is substantially flush with the box material output track 6. The horizontally arranged fine packaging surface is more suitable for the second operator to complete the fine packaging operation, especially operations such as attaching labels and / or soft packaging, more efficiently and comfortably at the foregoing height. In addition, the design that the fine packaging surface is adjacent to the box material output track 6 and is substantially flush with the box material output track 6 ensures that the second operator can easily and quickly push the packaging box containing the raw food materials onto the box material output track 6.

[0047] More preferably, the food material fine packaging platform 3 may further include a plurality of extended platen 34, see Figure 7 . The plurality of extended platen 34 are all arranged on the second platform frame 31 and are separately located within each reprocessing area 311, so that at least one extended platen 34 is evenly distributed within each reprocessing area 311. The extended platen 34 can be used as an extended part of the fine packaging platen 32 to provide more working space for the fine packaging of food materials, and can also be used for other purposes. The extended platen 34 is preferably selected as a tilting support structure similar to the storage platen 12. The tilting support structure is also used to keep the material box 200 in a tilted state, so that the second operator can more conveniently and quickly take away the raw food materials from the material box 200.

[0048] In the first embodiment and the second embodiment, the food material fine packaging platform 3 further includes a second empty box supply track 33 arranged on the second platform frame 31 and passing through each reprocessing area 311. The second empty box supply track 33 is an idle roller track or a flat plate structure. The second empty box supply track 33 is used to store empty packaging boxes or others, and is set to be higher than the box material output track 6 and the box material conveying track 4. During use, the second operator can temporarily place the unused packaging boxes on the second empty box supply track 33 so that they can obtain the packaging boxes at any time and complete the fine packaging operation of the raw food materials more quickly.

[0049] In the first embodiment and the second embodiment, the manual packaging line 100 for raw food materials may further include an empty box return track 7 arranged below the box material conveying track 4 and passing through the sorting and weighing platform 1, the food material cleaning platform 2, and the food material fine packaging platform 3, see Figure 1The empty box return track 7 is used to recycle the empty turnover boxes at the refined food packaging platform 3 and send them from the location where the empty box return track 7 is located back to the location where the sorting and weighing platform 1 is located. That is to say, after the refined packaging operation is completed, the turnover boxes from which the raw ingredients have been taken can be transferred back to the sorting and weighing platform 1 through the empty box return track 7 to achieve the reuse of the turnover boxes.

[0050] In summary, the manual packaging line 100 for raw ingredients in the embodiment of the present utility model can improve the packaging efficiency, reduce the packaging cost and production capacity fluctuations, and also take into account the improvement of packaging quality and consistency.
