Description

Technical Field

[0001] The embodiments of the present utility model relate to the technical field of packaging. More specifically, the present utility model relates to a sorting, weighing and dosing platform for raw food materials. Background Art

[0002] With the development of society and the acceleration of people's living rhythm, the requirements for the packaging efficiency and quality of food materials are getting higher and higher. Especially in the packaging process of raw food materials such as fruits, vegetables and seafood, it is necessary to sort the raw food materials, that is, pick out at least one grade of raw food materials and put them into corresponding grade material boxes (packaging boxes or turnover boxes). For example, when sorting, it is necessary to pick out the qualified fruits and put them into the material box, and then throw the unqualified fruits into the waste box or keep them in the raw material box. Another example is that when sorting is required, pick out the fruits with larger volume and no defects and put them into the high-grade material box, and then pick out the fruits with smaller volume and no defects and put them into the low-grade material box. Moreover, the packaging process often also needs to weigh and dose the raw food materials to ensure that the total weight of the raw food materials in the same grade material box is consistent and meets the set total weight index.

[0003] However, the current packaging method of raw food materials in the industry is still relatively traditional. It is necessary to rely on the operator to move the raw material box containing the raw food materials to the table carrying the weighing scale, and perform the sorting and weighing and dosing of the raw food materials on the table to ensure that each packaging box contains raw food materials of the same grade and the total weight of the raw food materials meets the predetermined total weight index. Although this processing method is simple and easy to implement, it has obvious deficiencies. First of all, manually moving the raw material box increases the labor intensity of the operator and reduces the individual work efficiency and the overall efficiency of food material packaging. Secondly, although the table supports multiple operators to perform the sorting and weighing and dosing of raw food materials in parallel, due to the lack of clear area division on the inner table, it is easy for operators to occupy and interfere with each other, and once again reduces the work efficiency of the operator and the overall efficiency of food material packaging. Summary of the Utility Model

[0004] In order to solve one or more of the above-mentioned technical problems, the present utility model provides a sorting, weighing and dosing platform for raw food materials, which can support multiple operators to complete the sorting, weighing and dosing of raw food materials in parallel, efficiently and without interference, and helps to improve the overall efficiency of food material packaging.

[0005] The present utility model provides a sorting, weighing and dispensing platform for raw food materials, which includes: a platform frame having a plurality of processing areas arranged at intervals in the horizontal direction; a material input track at least partially arranged within the platform frame and passing through each of the processing areas for storing raw material boxes containing raw food materials and allowing them to be pushed into each of the processing areas; a material output track at least partially arranged within the platform frame and passing through each processing area for collecting material boxes containing raw food materials and sending them out of the platform frame; a plurality of storage plates having storage surfaces, all of which are arranged on the platform frame and separately located in each of the processing areas, and the storage surfaces are used for carrying the raw material boxes containing raw food materials; a plurality of weighing plates having weighing surfaces, all of which are arranged on the platform frame and separately located in each of the processing areas, wherein the weighing surfaces are used for carrying weighing scales so that the weighing scales can weigh at least one grade of material boxes, and each grade of material box contains raw food materials matching its grade.

[0006] In the sorting, weighing and dispensing platform mentioned in the present utility model, the platform frame has a plurality of processing areas for multiple operators to perform sorting, weighing and dispensing operations in parallel. Each processing area is equipped with a storage plate, a weighing scale and a weighing plate. This ensures that an operator standing near any processing area can place an empty material box on the weighing scale in the same area, and directly obtain the raw material box actively or passively sent by the material input track in the same area to temporarily store it on the storage surface in the same area. Then, it is convenient for the operator to select at least one grade of raw food materials from this raw material box and successively put them into the aforementioned material box until the weighing result of the weighing scale reaches the total weight index. Then, the qualified and full material box is transferred to the material output track, and the material output track actively or passively sends it out of the platform frame to complete the sorting and weighing of the raw food materials. That is to say, the sorting, weighing and dispensing platform for raw food materials allows multiple operators to perform sorting and weighing of raw food materials in parallel and without interference by dividing areas, and realizes the efficient and easy handling of raw material boxes and material boxes by means of the material input track and the material input track. Thus, it can facilitate the operator to quickly and easily perform the sorting and weighing of raw food materials, ensure that the sorting, weighing and dispensing platform can support multiple operators to complete the sorting and weighing of raw food materials in parallel, efficiently and without interference, and helps to improve the overall efficiency of food packaging.

Detailed implementation manners

[0011] 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 part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present disclosure.

[0012] As Figure 1 and Figure 2 shown, the present utility model provides a sorting, weighing and dosing platform 100 for raw food materials. As Figure 1 and Figure 2 shown, the sorting, weighing and dosing platform 100 includes a platform frame 1, which has a plurality of processing areas 11 arranged at intervals in the horizontal direction. The plurality of processing areas 11 are preferably arranged in an array, especially one row with multiple columns. The sorting, weighing and dosing platform 100 further includes a material input track 2 and a material output track 3. The material input track 2 and the material output track 3 include idle roller tracks, belt conveyors and / or roller conveyors, wherein the idle track needs to be pushed manually to achieve passive material transportation, while the belt conveyor and the roller conveyor can achieve active material transportation. The material input track 2 is at least partially arranged within the platform frame 1 and passes through each processing area 11. During use, an operator or mechanical equipment is required to place a raw material box 300 containing raw food materials on the material input track 2, and then the material input track 2 transports it actively or passively to each processing area 11 to realize the supply of the raw material box and the raw food materials. The material output track 3 is at least partially arranged within the platform frame 1 and passes through each processing area 11. During use, the user can place a fully loaded (i.e., filled with raw food materials) material box 400 on the material output track 3, and then the material output track 3 sends it out of the platform frame 1, especially to the next process, such as the cleaning, boxing area or finished product storage area of raw food materials, etc.

[0013] As Figure 1 and Figure 2As shown in the figure, the sorting and weighing platform 100 further includes a plurality of storage pallets 4 having a storage tabletop. The storage pallets 4 are all arranged on the platform frame 1 and are separately located in each processing area 11 to ensure that each processing area 11 includes at least one storage pallet 4. The storage tabletop of the storage pallet 4 is used to carry the raw material box 300 containing the raw ingredients. The sorting and weighing platform 100 further includes a plurality of weighing pallets 5 having a weighing tabletop and a plurality of weighing scales 200 respectively arranged on the bearing surfaces of the respective weighing pallets 5. The plurality of weighing pallets 5 are all arranged on the platform frame 1 and are separately located in each processing area 11 to ensure that each processing area 11 includes at least one weighing pallet 5. Among them, the weighing scale 200 can weigh at least one grade of material boxes 400, and each grade of material box 400 contains raw ingredients matching its grade. It should be noted that during the sales process of the sorting and weighing platform 100, the customer has the option to decide whether to include the weighing scale 200. If the customer chooses not to purchase the weighing scale 200, it is necessary to ensure that a weighing scale 200 that can cooperate with the sorting and weighing platform 100 to implement its complete functions has been prepared before using the sorting and weighing platform 100.

[0014] In the sorting and weighing platform 100 mentioned in the present utility model, its platform frame 1 has a plurality of processing areas 11 for multiple operators to perform sorting and weighing operations in parallel. Each processing area 11 is equipped with a storage pallet 4, a weighing scale 200, and a weighing pallet 5. This ensures that an operator standing near any processing area 11 can place the empty material box 400 on the weighing scale 200 in the same area, and directly obtain the raw material box 300 actively or passively sent by the material input track 2 in the same area for temporary storage on the storage tabletop in the same area. Then, it is convenient for the operator to select at least one grade of raw ingredients from the raw material box 300 and successively put them into the aforementioned material box 400 until the weighing result of the weighing scale 200 reaches the total weight index. Then, the qualified and full material box 400 is transferred to the material output track 3, and the material output track 3 actively or passively sends it out of the platform frame 1 to complete the sorting and weighing of the raw ingredients. That is to say, the raw ingredient sorting and weighing platform 100 allows multiple 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 400 with the help of the material input track 2 and the material output track 3. Thus, it is convenient for the operator to quickly and easily perform the sorting and weighing of raw ingredients, ensuring that the sorting and weighing platform 100 can support multiple operators to complete the sorting and weighing of raw ingredients in parallel, efficiently, and without interference, which helps to improve the overall efficiency of food packaging.

[0015] In this embodiment, as Figure 1 and Figure 2As shown in the figure, the sorting and weighing platform 100 further includes a plurality of buffer plates 6 with buffer surfaces. The plurality of buffer plates 6 are all arranged on the platform frame 1 and are separately located in each processing area 11 to ensure that at least one buffer plate 6 is provided in each processing area 11. The buffer surface of the buffer plate 6 is used to temporarily store the material box 400 and the raw food ingredients loaded therein. In use, the high-grade material box 400 can be placed on the weighing scale 200, and then the low-grade material box 400 can be placed on the buffer plate 6. The operator picks out the high-grade raw food ingredients from the raw material box 300 and successively puts them into the high-grade material box 400, and at the same time, interspersedly picks out the low-grade raw food ingredients and successively puts them into the low-grade material box 400. When it is known through the weighing scale 200 that the high-grade material box 400 and the high-grade raw food ingredients successively loaded therein have met the total weight index, the operator needs to transfer the qualified and full high-grade material box 400 to the material output track 3, and the material output track 3 will send it out of the platform frame 1 actively or passively. Then, transfer the material box 400 filled or half-filled with low-grade raw food ingredients to the weighing scale 200. If it is not full, successively put the low-grade raw food ingredients from the raw material box 300 into the low-grade material box 400 until it is known through the weighing scale 200 that this material box 400 and the low-grade raw food ingredients successively loaded therein have met the total weight index. The operator stops the transfer operation and transfers the qualified and full low-grade material box 400 to the material output track 3, and the material output track 3 will send it out of the platform frame 1 actively or passively. By repeating the above process, the sorting and weighing of raw food ingredients can be continuously completed. It should be noted that the description of the use of the buffer plate 6 in this paragraph is only an example, and it can be flexibly adjusted according to needs in actual use and is not limited to this example.

[0016] It should be noted that if in the sorting process, it is not only necessary to load high-grade and low-grade raw food ingredients into different-grade material boxes 400, but also more grades of raw food ingredients need to be loaded into other-grade material boxes 400, then the number or area of the buffer plates 6 can be increased in each processing area 11. In addition, in the sorting of two grades, the unused buffer plates 6 or the remaining areas of the buffer surfaces can also be used for other purposes, such as storing waste boxes and the raw food ingredients loaded therein, etc.

[0017] In this embodiment, the sorting and weighing platform 100 further includes a plurality of spare planks 7 having spare table tops. The plurality of spare planks 7 are all arranged on the platform frame 1 and separately located in each processing area 11 to ensure that at least one spare plank 7 is provided in each processing area 11. The spare table top of the spare plank 7 is used to carry the raw material box 300 and / or the material box 400 and the native food ingredients loaded therein. Specifically, when performing sorting operations at two levels, the spare plank 7 can be used as a supplement to the storage plank 4 for temporarily storing the full-load raw material box 300 when the storage plank 4 is occupied. When performing sorting operations at three levels or more levels, in addition to the foregoing functions, the spare plank 7 can also be used as a supplement to the buffer plank 6 for temporarily storing one or two levels of material boxes 400. In addition, the spare plank 7 can also be used for other operations, such as storing the waste box and the native food ingredients therein, etc.

[0018] The storage table top of the storage plank 4 can be set to be higher or lower than the material input track 2, but this method requires the operator to transfer the full-load raw material box 300 from the material input track 2 to the storage table top of the storage plank 4 by way of holding and carrying. Therefore, in order to further reduce the labor intensity of the operator, the storage table top of the storage plank 4 near the edge of the platform frame 1 can be configured to be adjacent to the material input track 2 and substantially flush with the material-carrying conveying layer of the material input track 2. Thus, when the material input track 2 sends the raw material box 300 containing native food ingredients into the processing area 11 of the platform frame 1, the operator standing near the processing area 11 can directly pull the full-load raw material box 300 from the material input track 2 onto the storage table top of the storage plank 4. This operation can effectively reduce the labor intensity of the operator compared with the way of holding and carrying. Similarly, the weighing table top can also be set to make the weighing surface of the weighing scale 200 adjacent to the material output track 3 and substantially flush with the material-carrying conveying layer of the material output track 3, thereby ensuring that the operator can directly push the qualified and full-load material box 400 from the weighing scale 200 into the material output track 3 after weighing and further reducing the labor intensity of the operator. Preferably, the buffer surface of the buffer plank 6 near the edge of the platform frame 1 can be set to be adjacent to the weighing scale 22 and substantially flush with the weighing surface of the weighing scale 200, so that the operator can directly push the material box 400 containing native food ingredients from the buffer surface into the weighing scale 200 and further reduce the labor intensity of the operator.

[0019] Considering that the horizontal plane where the sorting and weighing platform 100 is located may not be the same as the horizontal plane where the user stands, the following definitions are made here. That is, the horizontal plane where the sorting and weighing platform 100 is located is defined as the first horizontal plane, and the horizontal plane where the user who uses the sorting and weighing platform 100 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, combined with the knowledge of ergonomics, the height of the material input track 2 relative to the second horizontal plane is preferably 1000 mm - 1300 mm, and the height of the material output track 3 relative to the second horizontal plane is preferably 500 mm - 800 mm. This not only directly limits the heights of the material input track 2 and the material output track 3, but also indirectly limits the heights of the buffer table board 6, the weighing scale 200, the storage table board 4 and the spare table board 7, and ensures that their heights are suitable for the operator to easily perform the corresponding operations. In addition, the feature that the storage table surface of the storage table board 4 is higher than the buffer table surface of the buffer table board 6 also ensures that the operator can perform a top-down handling operation that is easier than bottom-up when transferring the raw ingredients from the raw material box 300 to the material box 400.

[0020] In this embodiment, the buffer table board 6 and the spare table board 7 can both be preferably of a table structure, that is, the buffer table surface of the buffer table board 6 and the spare table surface of the spare table board 7 are both arranged along the horizontal direction. Among them, since the height of the buffer table board 6 relative to the second horizontal plane is 500 mm - 800 mm, it is more suitable for the operator to complete the boxing and weighing operations here by constructing its table surface as a plane arranged along the horizontal direction.

[0021] In this embodiment, the storage table board 4 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 operator to perform the material taking operation, the storage table board 4 is preferably selected as an inclined supporting structure, that is, the storage table board 4 includes an inclined supporting plate provided on the platform frame 1 and having a storage table surface, and a blocking structure provided at the lower end of the inclined supporting plate away from the platform frame 1 and used to prevent the raw ingredients from sliding off the storage table surface. Among them, the blocking structure can be optionally a guardrail, a baffle or other structures suitable for implementing blocking. When in use, the operator can directly pull the raw material box 300 filled with raw ingredients onto the inclined supporting plate of the storage table board 4, and use the blocking structure to prevent the raw material box 300 from sliding off the inclined supporting plate. At the same time, the inclined supporting plate is also used to keep the raw material box 300 in an inclined state, so that the operator can more conveniently and quickly take away the raw ingredients from the raw material box 300.

[0022] The sorting and weighing platform 100 further includes a storage and conveying track 8 disposed on the platform frame 1 and passing through each processing area 11, so as to ensure that at least one storage and conveying track 8 is provided in each processing area 11. The storage and conveying track 8 can be an idle roller path or a flat structure. The storage and conveying track 8 is used for storing empty raw material boxes 300 and / or material boxes 400, and is arranged higher than the material input track 2 and the material output track 3. The storage and conveying track 8 is used for storing turnover boxes and / or packaging boxes. In use, the operator can temporarily place the unused raw material boxes 300 and / or material boxes 400 on the storage and conveying track 8, so that the raw material boxes 300 and / or material boxes 400 can be obtained at any time and the sorting and weighing of the raw food ingredients can be completed more quickly.

[0023] The sorting and weighing platform 100 further includes a return conveying track 9 partially disposed within the platform frame 1 and passing through each processing area 11. The return conveying track 9 includes a belt conveyor and / or a roller conveyor, and is used for receiving the empty material boxes 400 and sending them back from a position outside the platform frame 1 to each processing area 11, and is arranged lower than the material input track 2 and the material output track 3. The return conveying track 9 can not only send the material boxes 400 (such as turnover boxes) that are outside the sorting and weighing platform 100, especially in the next process and have completed the sorting and weighing operation, from a position outside the platform frame 1 back to each processing area 11 to realize the continuous supply and repeated use of the material boxes 400; but also send the unused empty material boxes 400 into each processing area 11 to realize the supply of the material boxes 400.

[0024] In summary, the sorting and weighing platform 100 for raw food ingredients in the embodiment of the present utility model can support multiple operators to complete the sorting and weighing of raw food ingredients in parallel, efficiently and without interference, which helps to improve the overall efficiency of food packaging.
