Description

Technical Field

[0002] Currently, products such as coffee powder, protein powder, and pharmaceutical granules are often filled into packaging bags in a certain dosage to form bagged products for single use by users. And multiple bagged products are respectively placed in multiple spaced intervals of the inner tray of the packaging box for sale in a whole-box manner. At present, during the production process of bagged products, operators often need to perform operations such as cutting, weighing, and removing unqualified products on the packaging bags after filling the materials. Thus, during mass production, the workload of the operators is large and the efficiency is low.

[0003] In order to solve the above problems, although a cutting and sorting assembly line for bagged products has emerged in the industry, which can improve efficiency. However, for some bagged products with attached accessories (such as bagged coffee powder with a sugar powder packet attached, this sugar powder packet is an accessory and can be used by users to add the amount of sugar powder to the coffee powder according to their own taste requirements), operators still need to attach the accessories to the packaging bags of the bagged products. Thus, there is still a problem of large workload for the operators.

[0036] Next, in combination with the accompanying drawings and specific implementation modes, the present invention will be further described. It should be noted that, on the premise of no conflict, the following-described embodiments or technical features can be arbitrarily combined to form new embodiments.

[0037] As Figure 1-17 shown, a cutting and sorting production line for bagged products includes a cutting device 100 for cutting the packaging bags containing materials, a sorting machine 300, a guiding device 400, an auxiliary material attaching device 500, and a spacing adjusting device 600; the sorting machine 300, the auxiliary material attaching device 500, and the spacing adjusting device 600 are arranged in sequence; a plurality of conveying grooves 301 for the packaging bags to be inserted are provided on the sorting machine 300, and a pushing device 700 is installed on the sorting machine 300, and the pushing device 700 is used to push the packaging bags in the conveying grooves 301 along the conveying grooves 301 towards the auxiliary material attaching device 500; a turning area 310, a sampling area 320, a weighing area 330, a defective product removing area 340, a front output area 350, and a rear output area 360 are sequentially arranged on the sorting machine 300 along the pushing direction of the packaging bags; the guiding device 400 is used to guide a plurality of packaging bags cut by the cutting device 100 to the turning area 310 of the sorting machine 300, and a turning device 311 is arranged in the turning area 310, and the turning device 311 is used to turn over a plurality of packaging bags guided from the guiding device 400 to the sorting machine 300 so that the plurality of packaging bags are in a laterally erected state and are respectively inserted into a plurality of conveying grooves 301 one by one; the auxiliary material attaching device 500 is used to receive a plurality of packaging bags pushed out from the rear output area 360 and attach auxiliary materials to the packaging bags; the spacing adjusting device 600 is used to adjust the spacing between a plurality of packaging bags attached with auxiliary materials and transfer the packaging bags into the inner tray of the packaging box.

[0038] In use, after multiple packaging bags containing materials are cut by the cutting device 100, they are guided by the guiding device 400 to the turning area 310 of the sorting machine 300. Then, the multiple packaging bags are turned sideways by the turning device 311 so that the packaging bags are in a laterally erected state and are respectively inserted into multiple conveying grooves 301. Then, the packaging bags are pushed along the conveying grooves 301 by the pushing device 700 to the sampling area 320. After sampling in the sampling area 320, the packaging bags are then pushed by the pushing device 700 to the weighing area 330. After weighing in the weighing area 330, the pushing device 700 continues to push the packaging bags along the conveying grooves 301 and pushes the packaging bags to the unqualified product rejection area 340. In the unqualified product rejection area 340, the packaging bags with unqualified weighing are rejected. After that, the pushing device 700 continues to push the packaging bags with qualified weighing along the conveying grooves 301. If there are packaging bags with unqualified weighing among the multiple packaging bags of the same batch that are guided to the turning area 310 of the sorting machine 300 at one time by the guiding device 400, the remaining packaging bags with qualified weighing are output through the front output area 350. If all the multiple packaging bags of the same batch have qualified weighing, the multiple packaging bags of this batch are pushed out from the rear output area 360. The auxiliary material attaching device 500 is used to receive the multiple packaging bags pushed out from the rear output area 360 and attach the auxiliary materials to the packaging bags. Then, the spacing between the packaging bags is adjusted by the spacing adjusting device 600, and then the multiple packaging bags with adjusted spacing are transferred onto the inner tray of the packaging box. Therefore, a cutting and sorting production line for bagged products provided by the present invention, by combining the cutting device 100, the sorting machine 300, the guiding device 400, the auxiliary material attaching device 500, and the spacing adjusting device 600, can cut the packaging bags by using the cutting device 100 and attach the auxiliary materials to the packaging bags by using the auxiliary material attaching device 500, so that there is no need for manual cutting of the packaging bags and attaching of the auxiliary materials to the packaging bags, which can reduce the participation of operators, thereby reducing the workload of operators and improving production efficiency. Moreover, the spacing between the packaging bags can also be adjusted by the spacing adjusting device 600, so as to meet the packaging requirements of different inner tray spacing intervals of different sizes and be applicable to more different packaging boxes.

[0039] The cutting device 100 includes a base 110, a plurality of fixed cutting dies 120 fixed on the base 110, a plurality of abutting tool holders 130 fixed on the base 110 and respectively located below the plurality of fixed cutting dies 120 in a one-to-one correspondence, a support unit provided on the base 110, a packaging bag push plate 140 movably mounted on the support unit, a first elastic element 141, a moving seat 150, a driving device 160, a plurality of movable cutting dies 170 fixed on the moving seat 150 and respectively corresponding to the plurality of fixed cutting dies 120 in a one-to-one correspondence, a plurality of positioning seats 180 respectively corresponding to the plurality of fixed cutting dies 120 in a one-to-one correspondence, a plurality of tear-notch cutting blades 200 fixed on the moving seat 150 and respectively corresponding to the plurality of abutting tool holders 130 in a one-to-one correspondence, and a pushing block 210 provided on the moving seat 150 and used for pushing the packaging bag push plate 140 towards the base 110; the driving device 160 is used for driving the moving seat 150 to move towards the base 110 and also for driving the moving seat 150 to move away from the base 110; the movable cutting die 170 is used for cooperating with the corresponding fixed cutting die 120 to form a cutting tool for cutting the packaging bag; a slit 131 for the corresponding tear-notch cutting blade 200 to extend into is provided on the abutting tool holder 130; the packaging bag push plate 140 is located below the abutting tool holder 130 and is used for pushing the packaging bag; the first elastic element 141 abuts between the packaging bag push plate 140 and the base 110 and is used for providing an elastic force to urge the packaging bag push plate 140 to move away from the base 110; the positioning seat 180 is used for abutting the packaging bag against the corresponding fixed cutting die 120 and abutting tool holder 130, and a through slot 182 for the tear-notch cutting blade 200 to pass through is provided on the positioning seat 180; a moving cooperation unit movably mounted on the moving seat 150 is provided on each positioning seat 180, and a second elastic element 191 is abutted between each moving cooperation unit and the moving seat 150, and the second elastic element 191 is used for providing an elastic force to urge the positioning seat 180 to move away from the moving seat 150.During use, when multiple packaging bags reach the positions of the fixed cutting dies 120 downward, the driving device 160 drives the movable seat 150 to move toward the direction close to the base 110. At this time, the abutting block 210, the movable cutting die 170, and the positioning seat 180 move toward the direction close to the base 110 along with the movable seat 150, and the packaging bag push plate 140 is pushed toward the direction close to the base 110 by the abutting block 210. At this time, the first elastic element 141 is compressed by the packaging bag push plate 140, and the positioning seat 180 is used to push the packaging bag against the corresponding The fixed cutting die 120 and the abutting knife seat 130 are respectively fixed, and since the positioning seat 180 can not continue to move with the movable seat 150 after abutting the packaging bag against the fixed cutting die 120 and the abutting knife seat 130, at this time, the easy-tear cutting blade 200 still moves with the movable seat 150 relative to the positioning seat 180 toward the direction close to the base 110 and extends from the penetration groove 182, and the easy-tear cutting blade 200 is used to poke a dot-shaped easy-tear opening on the packaging bag. In this process, the movable cutting die 170 cooperates with the fixed cutting die 120 to cut the packaging bag, and the packaging bag to be packaged is After the cutting and easy-tear processing are completed, the driving device 160 drives the movable seat 150 to move in the direction away from the base 110, and the top block 210 and the movable cutting die 170 move in the direction away from the base 110 along with the movable seat 150, and the easy-tear cutting blade 200 moves into the penetration groove 182 of the positioning seat 180 along with the movement of the movable seat 150, and in the process of the movable seat 150 gradually moving in the direction away from the base 110, the positioning seat 180 is separated from the packaging bag to remove the top force on the packaging bag, and then the top block 210 and the packaging bag push plate 140 are moved. 0 separation, the packaging bag push plate 140 moves away from the base 110 under the elastic force of the first elastic element 141, and pushes the packaging bag to separate from the fixed cutting die 120, thereby preventing the packaging bag from adhering to the fixed cutting die 120. Therefore, by adopting the above structure, the cutting device 100 has the functions of packaging bag cutting and easy-tear processing. Moreover, after the packaging bag is cut, the packaging bag can be pushed outward by the packaging bag push plate 140 to separate the packaging bag from the fixed cutting die 120, thereby preventing the packaging bag from adhering to the fixed cutting die 120.

[0040] The fixed cutting die 120 is provided with a cutting edge 121 for the movable cutting die 170 to be embedded. The inner bottom wall of the cutting edge 121 is formed into a cutting matching surface 122 that is concave in the middle and convex at both ends. The bottom of the movable cutting die 170 is provided with a cutting forming surface 171 that matches the cutting matching surface 122, so that the cutting position of the packaging bag matches the cutting forming surface 171, so that the cut packaging bag is more recognizable and anti-counterfeiting, and the difference in product packaging can be highlighted.

[0041] Specifically, guide bars 172 are provided on both sides of the movable die 170. The two guide bars 172 are movably inserted into the blade edge 121. Thus, during the movement of the movable die 170 along with the moving seat 150, through the cooperation between the guide bars 172 and the blade edge 121, the smoothness of the movement of the movable die 170 can be improved.

[0042] Preferably, a collection cavity 112 communicating with the blade edge 121 is formed on the base 110, and a pushing device 250 for pushing the cutting waste out of the collection cavity 112 is further installed on the base 110. The cutting waste cut out is pushed from the blade edge 121 to the collection cavity 112 by the movable die 170, and the cutting waste collected in the collection cavity 112 can be pushed outwards by the pushing device 250. Thus, there is no need for manual removal of the cutting waste, and the working intensity of the operator can be reduced.

[0043] Among them, in this embodiment, the pushing device 250 includes a screw propelling shaft rotatably installed in the collection cavity 112 and a second driving motor for driving the screw propelling shaft to rotate. Thus, when the second driving motor drives the screw propelling shaft to rotate, the cutting waste in the collection cavity 112 can be pushed out. Of course, in addition, the pushing device 250 can adopt any existing pushing device on the market as long as it can push the cutting waste out of the collection cavity 112. However, by combining the pushing device 250 with a screw propelling shaft and a second driving motor, while the cutting waste in the collection cavity 112 can be pushed out, it is also convenient for installation.

[0047] The support unit includes at least two support pin shafts 113 provided on the base 110. An installation hole unit is provided on the packaging bag push plate 140. The installation hole unit includes at least two installation holes that respectively correspond to the at least two support pin shafts 113 of the support unit one by one and through which the corresponding support pin shafts 113 pass. By adopting the above structure, the packaging bag push plate 140 can move along the at least two support pin shafts 113 of the support unit, and the smoothness of the movement of the packaging bag push plate 140 can be improved.

[0048] A first elastic element 141 that abuts between the packaging bag push plate 140 and the base 110 is sleeved on each support pin shaft 113, so as to ensure the elastic reset force of the packaging bag push plate 140.

[0049] The first elastic element 141 is a first spring. Of course, in addition, the first elastic element 141 can also be an elastic element such as an elastic sheet. However, using the first spring as the first elastic element 141 is the optimal implementation mode of the present invention, which can reduce costs and facilitate installation.

[0050] The moving seat 150 is provided with a plurality of installation units that respectively correspond to the moving cooperation units of the plurality of positioning seats 180 one by one. The moving cooperation unit includes at least two moving pin shafts 183 that are fixed on the positioning seat 180 and arranged horizontally.

Specifically, an inner side wall of the conveying groove 301 far from the corresponding receiving groove 312 is formed as a limiting wall for the packaging bag to abut against when the flipping plate 313 is turned upwards, and the bottom wall of the conveying groove 301 at the position corresponding to the flipping area 310 is formed as a supporting wall for supporting the packaging bag. When the plurality of packaging bags cut by the cutting device 100 are guided to the plurality of receiving grooves 312 by the guiding device 400, and the left sides of the packaging bags are located in the conveying grooves 301, the flap driving component drives the plurality of flipping plates 313 to rotate upwards synchronously. The left sides of the lying flat packaging bags abut against the limiting wall, and the packaging bags are turned over to be laterally erected and located in the conveying grooves 301 under the pushing action of the flipping plates 313, and then the packaging bags are pushed along the conveying grooves 301 by the pushing device 700.

[0061] Certainly, in addition to this, the flipping plate driving component can also adopt the combination of a motor and a gear assembly, etc., as long as it can drive the plurality of flipping plates 313 to rotate synchronously. However, adopting the combination of the first driving cylinder 315, the linkage plate 316, and the plurality of push claws 317 for the flipping plate driving component is the optimal implementation mode of the present invention. While driving the plurality of flipping plates 313 to rotate synchronously, it can also reduce costs.

[0062] The sorting machine 300 includes a top-mounted plate seat, and the conveying groove 301 is formed on the top-mounted plate seat.

[0063] The sampling area 320 is provided with a sampling device 321 located below the top-mounted plate seat. The part of the conveying groove 301 located in the sampling area 320 is formed as a sampling through groove section 322 with an open lower end. The sampling device 321 includes a sampling opening cover plate 323 slidably installed below the top-mounted plate seat, a sampling box located below the sampling opening cover plate 323, and a second driving cylinder 325.

When the second driving cylinder 325 drives the sampling opening cover plate 323 to move until the sampling through groove 326 is directly opposite to the sampling through groove section 322, the packaging bags pushed to the sampling through groove section 322 can fall into the sampling box through the sampling through groove section 322 and the sampling through groove 326, thereby realizing sampling. When sampling is not required, by driving the sampling opening cover plate 323 to move until the sampling closing plate part 327 is directly opposite to the sampling through groove section 322 by the second driving cylinder 325, the sampling through groove section 322 can be covered by using the sampling closing plate part 327, and then the pushing device 700 can continue to push the packaging bags along the sampling through groove section 322 towards the weighing area 330. By adopting the above structure, the sampling device 321 can be used for sampling, so that manual sampling by operators is not required, and the workload of operators can be further reduced.

[0064] Specifically, the part of the conveying trough 301 located in the weighing area 330 is formed as a weighing through groove section 331 with an open lower end. A plurality of weighing components 332 are provided in the weighing area 330 and are respectively installed inside the lower ends of a plurality of weighing through groove sections 331 one by one. Thus, the weighing components 332 can be used to weigh the packaging bags, eliminating the need for operators to manually hold the weighing components 332 to weigh the packaging bags, which can further reduce the workload of the operators.

[0065] The part of the conveying trough 301 located in the defective product rejection area 340 is formed as a rejection through groove section 341 with an open lower end.

For the packaging bags that fail to pass the weighing, the third driving cylinder 344 of the corresponding opening and closing device 342 drives the rejection cover plate 343 to rotate downward to open the rejection through groove section 341. The packaging bags pushed to the rejection through groove section 341 can fall through the rejection through groove section 341 onto the rejection conveyor line 345 and be conveyed out through the rejection conveyor line 345. For the packaging bags that pass the weighing, when the third driving cylinder 344 of the corresponding opening and closing device 342 drives the rejection cover plate 343 to rotate upward, the corresponding rejection through groove section 341 can be covered by the rejection cover plate 343, so that the packaging bags that pass the weighing can continue to move forward to the front output area 350 along the corresponding rejection through groove section 341 under the pushing of the pushing device 700.

The packaging bags with qualified weighing pushed to the front output through groove section 351 can fall onto the front conveyor line 354 through the front output through groove section 351 and the front output through groove 356, and are conveyed out through the front conveyor line 354, thus realizing front output. When all the packaging bags in the same batch have qualified weighing, the fourth driving cylinder 355 drives the front output opening cover plate 353 to move until the front output closed plate part 357 is aligned with the front output through groove section 351, so as to use the front output closed plate part 357 to cover the front output through groove section 351, and then the pushing device 700 can push the packaging bags along the front output through groove section 351 to the rear output area 360 continuously.

[0067] The part of the conveying groove 301 located in the rear output area 360 is formed into a rear output groove section 361 with a closed lower end. That is, the bottom of the rear output groove section 361 has a groove bottom wall for supporting the packaging bags, so that the packaging bags can be pushed along the rear output groove section 361 to the auxiliary material attaching device 500 under the pushing of the pushing device 700.

The auxiliary material attaching device 500 further includes a lifting device 550 for promoting the accommodating frame 513 to lift upward relative to the material loading base 511 when the material loading mechanism 510 is in the auxiliary material adhesion position. When the translation device 520 drives the material loading mechanism 510 to move to the auxiliary material adhesion position, the lifting device 550 promotes the accommodating frame 513 to lift upward relative to the material loading base 511, so that the middle and upper parts of the packaging bag with the lower end accommodated in the accommodating frame 513 are exposed from the material loading base 511, and then the auxiliary material is adhered to the middle and upper parts of the packaging bag through the auxiliary material attaching mechanism 530. While the packaging bag is pushed into the accommodating frame 513 through the conveying groove 301 and in a laterally erected state by using the conveying groove 301 and the flipping device 311, by combining the material loading mechanism 510 with the material loading base 511 and the plurality of accommodating frames 513, the lifting device 550 can be used to promote the material loading base 511 to lift upward, so that the middle and upper parts of the packaging bag in a laterally erected state are exposed, which is convenient for the auxiliary material attaching mechanism 530 to adhere the auxiliary material to the middle and upper parts of the packaging bag.

[0071] The lifting device 550 includes a lifting plate 551 and a plurality of jacking frames 552 fixed on the lifting plate 551 and corresponding to the plurality of accommodating frames 513 one by one.

From the end of the descending slope 558 close to the stop slope 556 to the end close to the second flat track 554, the descending slope 558 gradually slopes downward. When the loading seat 511 moves from the receiving position toward the auxiliary material adhesion position driven by the translation device 520, the rollers 515 of each accommodating frame 513 first roll horizontally along the first flat track 553 of the corresponding jacking frame 552, and then gradually roll upward along the ascending slope 557. At this time, the accommodating frame 513 gradually moves upward relative to the loading seat 511 driven by the lower rod 514.

The upper middle part of the packaging bag whose lower end is accommodated in the accommodating frame 513 is exposed from the loading seat 511. After the auxiliary material attaching mechanism 530 attaches the auxiliary material to the upper middle part of the packaging bag, the translation device 520 drives the loading seat 511 to move from the auxiliary material adhesion position toward the discharging position. At this time, the rollers 515 of each accommodating frame 513 first move from the stop slope 556 to the descending slope 558 and gradually roll downward along the descending slope 558. At this time, the accommodating frame 513 descends relative to the loading seat 511. When the roller 515 of the accommodating frame 513 rolls to the second flat track 554, the accommodating frame 513 descends and is accommodated in the storage cavity 512 of the loading seat 511.
