Description

Technical Field

[0001] This invention relates to the field of flexible packing and conveying technology, specifically a flexible packing and conveying machine based on multi-specification product category switching. Background Technology

[0002] In the bottled water production sector, due to differences in consumption scenarios (such as outdoor portability and household stockpiling), products often cover multiple sizes, including small bottles under 550mL and large bottles of 1.5L and above. Furthermore, with the increasing fragmentation of orders, production lines need to frequently switch between different bottle types for packing tasks. When faced with multi-size combinations of orders from e-commerce platforms, production needs to be split up.

[0003] Current technical solutions in the flexible packaging field for bottled water generally suffer from poor process coordination and efficiency bottlenecks, making it difficult to adapt to the needs of efficient and continuous automated production lines. On the one hand, traditional single-channel transfer mechanisms mostly use a single gripper or multiple grippers with synchronous movements. Their motion patterns are fixed and cannot achieve alternating cycles. The grippers have a large amount of ineffective idle waiting time, which not only leads to low efficiency of individual machines, but also slows down the overall production rhythm due to the discontinuous action rhythm. On the other hand, existing conveyor mechanisms mostly use conveyor belts running in the same direction for connection, resulting in a single material flow direction. There is a lack of chain conveyor belts with reverse or counter-directional layouts to cooperate with them. This makes it difficult to form an effective buffer and arrangement space between the transfer and sorting stages of bottled water. This not only limits the ability to flexibly adjust the arrangement of bottled water of different specifications, but also affects the coordination of upstream and downstream equipment due to process interruptions. Overall, it is difficult to achieve high efficiency, high flexibility, and smooth operation.

[0004] Therefore, developing a new type of packing system that can introduce an alternating gripping and releasing mechanism to eliminate waiting gaps and utilize a reverse conveyor belt to achieve seamless process connection is of urgent practical significance for improving the overall efficiency of the production line and enhancing the ability to adapt to multiple specifications. Summary of the Invention

[0005] The purpose of this invention is to provide a flexible packing conveyor based on multi-specification product category switching, in order to solve the problems mentioned in the background art above.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] Based on the flexible packing conveyor for switching between multiple specifications and categories, along the feeding direction of the flexible packing conveyor, a first frame, a first support frame, a second support frame and a second frame are arranged sequentially on the flexible packing conveyor, and a third support frame is installed on the outer side of the second frame near the second support frame.

[0008] Wherein, the end of the first frame away from the first support frame is connected to the upstream single-channel bottle conveying device;

[0009] The first frame is provided with an alignment mechanism at the top for auxiliary conveying and guiding of bottled water. The second support frame is provided with a conveying mechanism at the top for sequentially arranging bottled water. The first support frame is provided with a transfer mechanism inside for transferring bottled water from the top of the first frame to the conveying mechanism. The third support frame is provided with a receiving mechanism inside for transporting the neatly arranged bottled water from the top of the conveying mechanism as a whole.

[0010] Furthermore, a first conveyor belt is installed on the inner side of the first frame, and a second conveyor belt is installed on the inner side of the second frame. Both the first and second conveyor belts are powered by an external drive device to transport bottled water.

[0011] Furthermore, multiple sets of lifting cylinders are fixedly installed on both sides of the first frame, and a support plate is fixedly connected to the output end of the lifting cylinder;

[0012] The alignment mechanism includes multiple sets of sleeves fixed to the top of the support plate. A sliding frame is slidably connected inside the sleeve. A transverse electric push rod for driving the sliding frame to move horizontally is fixedly installed on the outer side of one end of the sleeve. Multiple sets of positioning frames are fixedly connected to the side wall of the sliding frame. Multiple sets of screw holes are opened on the side wall of the positioning frame, and a guide wheel assembly is fixedly installed on the positioning frame through the screw holes. The guide wheel assembly consists of multiple sets of guide wheels.

[0013] Furthermore, the conveying mechanism consists of two chain conveyor belts that turn in opposite directions, and the chain conveyor belts are driven by an external drive device to arrange the bottled water.

[0014] Furthermore, the material transfer mechanism includes two first electric lifting push rods fixed to the mounting slots on the top of the first support frame. The top of the first support frame is movably connected to two first drive gears and two second drive gears via bearings. A polygonal limiting groove is provided through the center of the first drive gear, and a matching connecting rod is slidably connected in the polygonal limiting groove. The top end of the corresponding connecting rod and the top end of the corresponding first electric lifting push rod are connected to the bottom of the same horizontal plate. The top end of the connecting rod is rotatably connected to the bottom of the horizontal plate, and the top end of the first electric lifting push rod is fixedly connected to the bottom of the horizontal plate.

[0015] Furthermore, a through slot is provided at the top of the first support frame and directly below the center of the first drive gear. The bottom end of the connecting rod is fixedly connected to the mounting sleeve through the through slot. A first electric clamping claw is fixedly installed inside the mounting sleeve by bolts. A servo motor for rotating the second drive gear is fixedly installed at the top of the inner wall of the first support frame.

[0016] The first drive gear and the second drive gear are connected by a chain.

[0017] Furthermore, the receiving mechanism includes a slide block, and multiple sets of brackets are fixedly installed on the top of the inner wall of the third support frame. The inner side of the bracket is provided with a slide rod and an electric reciprocating screw. The slide block cooperates with the electric reciprocating screw and the slide rod respectively through the threaded groove and the sliding groove opened on its side wall.

[0018] Furthermore, a second electric lifting push rod is fixedly connected to the bottom end of the slide block, a third electric lifting push rod is fixedly installed on the top of the inner wall of the third support frame, a bearing frame is fixedly connected to the bottom end of the second electric lifting push rod, and multiple sets of second electric clamping claws are fixedly connected to the bottom of the bearing frame by bolts.

[0019] Furthermore, a baffle plate is fixedly connected to the bottom end of the third electric lifting push rod.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] By employing two opposing-direction chain conveyor belts, the system cleverly integrates guiding, material transfer, and arranging functions, achieving a smooth transition from bottled water alignment to row arrangement. The alternating "left grip → right grip → left place → right place" operation mode of the left and right first electric grippers creates a continuous work cycle for gripping, transferring, and placing, completely eliminating idle time for individual first electric grippers while waiting for bottled water to arrive, significantly improving material transfer efficiency. Simultaneously, the system flexibly adjusts the number of grippers and the number of alternating grips to precisely adapt to the single-row quantity requirements of different bottle sizes—for example, large bottles are arranged in rows of 2 via 2 alternations, while small bottles are arranged in rows of 6 via 6 alternations. This flexible design, combined with the precise control of the row number by the receiving mechanism, enables the system to quickly and neatly form the target formation (e.g., 2 rows of large bottles, 4 rows of small bottles) on the second conveyor belt, ultimately achieving seamless integration with downstream packing equipment. The entire process is tightly integrated with minimal waiting time, significantly improving the overall efficiency and adaptability of the packing process while ensuring arrangement accuracy.

Detailed Implementation

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Example 1: As Figures 1-8 As shown, a flexible packing conveyor based on multi-specification category switching has a first frame 101, a first support frame 201, a second support frame 202 and a second frame 102 arranged sequentially on the flexible packing conveyor along the feeding direction of the flexible packing conveyor. A third support frame 203 is installed on the outer side of the second frame 102 near the second support frame 202.

[0034] Along the feeding direction of the flexible case conveyor, the end of the first frame 101 furthest from the first support frame 201 is precisely connected to the upstream single-channel bottle conveyor to receive the bottled water conveyed upstream. After being guided and aligned by the alignment mechanism, transferred by the transfer mechanism, and arranged by the conveying mechanism, the end of the second frame 102 furthest from the second support frame 202 is tightly connected to the downstream case packing equipment. The receiving mechanism then transfers the arranged bottled water to the case packing equipment, forming a complete closed loop of "upstream feeding - intermediate flexible conveying - downstream case packing". Throughout the process, the grippers and guide components are used to adjust and adapt to large and small bottle sizes, and the connection structure at both ends has flexible adaptability.

[0035] The top of the first frame 101 is provided with an alignment mechanism for auxiliary conveying and guiding bottled water. The top of the second support frame 202 is provided with a conveying mechanism for sequentially arranging bottled water. The inner side of the first support frame 201 is provided with a transfer mechanism for transferring the bottled water on the top of the first frame 101 to the conveying mechanism. The inner side of the third support frame 203 is provided with a receiving mechanism for transporting the neatly arranged bottled water on the top of the conveying mechanism as a whole.

[0036] A first conveyor belt 901 is installed on the inner side of the first frame 101, and a second conveyor belt 902 is installed on the inner side of the second frame 102. Both the first conveyor belt 901 and the second conveyor belt 902 are powered by an external drive device to realize the transport of bottled water.

[0037] Multiple sets of lifting cylinders 3 are fixedly installed on both sides of the first frame 101, and a support plate is fixedly connected to the output end of the lifting cylinder 3.

[0038] The alignment mechanism includes multiple sets of sleeves 401 fixed to the top of the support plate. A sliding frame 402 is slidably connected inside the sleeve 401. A transverse electric push rod 403 for driving the sliding frame 402 to move horizontally is fixedly installed on the outer side of one end of the sleeve 401. Multiple sets of positioning frames 404 are fixedly connected to the side wall of the sliding frame 402. Multiple sets of screw holes are opened on the side wall of the positioning frame 404, and a guide wheel assembly 405 is fixedly installed on the positioning frame 404 through the screw holes. The guide wheel assembly 405 is composed of multiple sets of guide wheels.

[0039] Note: The number of guide roller assemblies 405 needs to be flexibly adjusted according to the height of the bottled water. When the bottled water is taller, increase the number of guide roller assemblies 405 on the positioning frame 404 to ensure more stable guidance and support for the bottle body. When the bottled water is shorter, reduce the number of guide roller assemblies 405 to avoid interference between the guide rollers and the bottom of the bottle body.

[0040] The conveying mechanism consists of two chain conveyor belts 501 that turn in opposite directions. The chain conveyor belts 501 are driven by an external drive device to arrange the bottled water.

[0041] The material transfer mechanism includes two first electric lifting push rods 601 fixed in the mounting slots on the top of the first support frame 201. The top of the first support frame 201 is movably connected to two first drive gears 602 and two second drive gears 603 via bearings. A polygonal limiting groove is provided through the center of the first drive gear 602, and a matching connecting rod 604 is slidably connected in the polygonal limiting groove. The top of the corresponding connecting rod 604 and the top of the corresponding first electric lifting push rod 601 are connected to the bottom of the same horizontal plate 605. The top of the connecting rod 604 is rotatably connected to the bottom of the horizontal plate 605, and the top of the first electric lifting push rod 601 is fixedly connected to the bottom of the horizontal plate 605.

[0042] A through slot is provided on the top of the first support frame 201 and directly below the center of the first drive gear 602. The bottom end of the connecting rod 604 is fixedly connected to the mounting sleeve 606 through the through slot. The first electric clamping claw 607 is fixedly installed inside the mounting sleeve 606 by bolts. A servo motor 608 for rotating the second drive gear 603 is fixedly installed on the top of the inner wall of the first support frame 201.

[0043] The first drive gear 602 and the second drive gear 603 are connected by a chain 609.

[0044] Example 2: Figure 1 , Figure 8 As shown, the receiving mechanism includes a slide block 701. Multiple sets of brackets are fixedly installed on the top of the inner wall of the third support frame 203. A slide rod and an electric reciprocating screw 9 are provided on the inner side of the bracket. The electric reciprocating screw 9 is rotatably connected to the bracket, and the slide rod is fixedly connected to the bracket. The slide block 701 cooperates with the electric reciprocating screw 9 and the slide rod respectively through the threaded groove and sliding groove opened on its side wall.

[0045] The bottom end of the slide block 701 is fixedly connected to a second electric lifting push rod 702, and the top of the inner wall of the third support frame 203 is fixedly installed with a third electric lifting push rod 8. The bottom end of the second electric lifting push rod 702 is fixedly connected to a bearing frame 703, and the bottom of the bearing frame 703 is fixedly connected with multiple sets of second electric clamping claws 704 by bolts.

[0046] The bottom end of the third electric lifting push rod 8 is fixedly connected to a baffle plate 10.

[0047] Combining Embodiment 1 and Embodiment 2, the working principle of the present invention is as follows:

[0048] Along the feeding direction of the flexible case conveyor, the end of the first frame 101 furthest from the first support frame 201 is precisely connected to the upstream single-channel bottle conveyor to receive the bottled water conveyed upstream. After being guided by the alignment mechanism, gripped and transferred by the transfer mechanism in a "row-column" manner, and neatly arranged by the conveying mechanism, the end of the second frame 102 furthest from the second support frame 202 is tightly connected to the downstream case packing equipment. The receiving mechanism transfers the neatly arranged bottled water to the second conveyor belt 902, and finally conveys it to the case packing equipment to complete the case packing. Throughout the process, the number and arrangement of the grippers can be adjusted to accommodate different sizes of bottled water. A typical example is "two bottles (large bottled water) per row, two columns in total, and six bottles (small bottled water) per row, four columns in total," which can be flexibly adjusted. Another example is "six small bottles (transferred in three batches) and two large bottles (transferred in one batch)."

[0049] When the guided bottled water moves along the first conveyor belt 901 to below the first support frame 201, the transfer mechanism is activated to complete the transfer from the first conveyor belt 901 to the transfer mechanism, and the number of transfers can be adapted to meet the single-row quantity requirements of large and small bottles:

[0050] Servo motor 608 drives second drive gear 603 to rotate, which in turn drives first drive gear 602 to rotate synchronously via chain 609. The polygonal limiting groove of first drive gear 602 slides with connecting rod 604, which both drives connecting rod 604 to rotate (adjusting the horizontal position of the clamping claw) and allows connecting rod 604 to rise and fall with first electric lifting push rod 601 (connected via cross plate 605) (adjusting the height of clamping claw). Finally, the first electric clamping claw 607 on the mounting sleeve 606 at the bottom of connecting rod 604 performs the transfer action of "descending, clamping, rising, rotating, descending, and releasing".

[0051] The left gripper first places the first bottle of water into the preset position of the conveyor mechanism, then rotates back to its original position to wait for the third bottle of water; the right gripper then places the second bottle of water into the corresponding position of the conveyor mechanism, then rotates back to its original position to wait for the fourth bottle of water.

[0052] Repeat the alternating rhythm of "grab left → grab right → release left → release right" to achieve continuous transfer of bottled water and avoid inefficiency caused by waiting for a single gripper.

[0053] The two first electric grippers 607 adapt to the "single row quantity" requirements of different bottled water sizes by "alternating gripping times" and "dispensing position planning":

[0054] Large bottle of water (2 bottles in a row): A single row can be completed by alternating grabbing twice: the left claw grabs the first large bottle of water and places it in the "left position of the single row" of the conveyor mechanism; the right claw grabs the second large bottle of water and places it in the "right position of the single row" of the conveyor mechanism. After two alternating grabbing, the "two bottles in a row" formation is formed directly without any additional adjustment.

[0055] Small bottles of water (6 bottles per row): A single row needs to be completed by 6 alternating grabs, and the placement positions are planned in the order of "left → right → left → right → left → right": 1st grab (left claw): place to "position 1 of the row"; 2nd grab (right claw): place to "position 2"; 3rd grab (left claw): place to "position 3"; 4th grab (right claw): place to "position 4"; 5th grab (left claw): place to "position 5"; 6th grab (right claw): place to "position 6"; After 6 alternations, the 6 small bottles of water are arranged closely together horizontally on the conveyor mechanism, forming a complete formation of "6 bottles in a row".

[0056] The number of rows depends entirely on the number of times the slide 701 of the receiving mechanism moves: each time the slide 701 moves once, it transfers one "single row" from the chain conveyor belt 501 to the second conveyor belt 902; after several moves, several rows are stacked on the second conveyor belt 902. The specific actions are as follows:

[0057] Single gripping and transfer of slide 701 (single row): Gripping a single row: The electric reciprocating screw 9 on the third support frame 203 drives the slide 701 (sliding along the slide rod) to move above the "gripping position" of the chain conveyor belt 501; the second electric lifting push rod 702 drives the support frame 703 to descend, and the second electric clamping claw 704, which is adjusted according to the number of bottles in a single row (two sets of second electric clamping claws 704 are used to grip 2 bottles in a single row for large bottles, and six sets of second electric clamping claws 704 are used to grip 6 bottles in a single row for small bottles), clamps the single row;

[0058] Simultaneously, the third electric lifting push rod 8 lowers the baffle plate 10 to prevent the bottle from tipping over. The slide block 701, carrying the clamped "single row," moves above the second conveyor belt 902. The second electric lifting push rod 702 lowers, and the second electric gripper 704 releases its grip, placing the single row onto the second conveyor belt 902. Then, the slide block 701 returns to its original position, ready for the next gripping. The number of times the slide block 701 moves equals the number of rows (core adaptation): large bottles require "2 rows": the slide block 701 repeats the above "grip → transfer → return" action twice—the first time transferring the first single row to the second conveyor belt 902, and the second time transferring the second single row to the second conveyor belt 902 (side by side with the first row / arranged according to the spacing), ultimately forming a "2 rows, 2 bottles per row" formation on the second conveyor belt 902.

[0059] The small bottles need to be arranged in "4 rows": Slide 701 repeats the above action 4 times—each time transferring one "single row of 6 bottles" to the second conveyor belt 902, after 4 times, forming a "4 rows, 6 bottles per row" formation. (Note: The second conveyor belt 902 remains stationary during the transfer by slide 701 to ensure that each row can be smoothly stacked in the preset position without shifting.)

[0060] After the target number of rows is stacked (2 rows of large bottles and 4 rows of small bottles), the second conveyor belt 902 (driven externally) transports the complete "multi-row bottled water" to the end of the second frame 102 away from the second support frame 202. Since this end is closely connected to the downstream packing equipment, the multi-row bottled water directly enters the packing equipment, completing the complete closed loop of "upstream feeding - alternating transfer - multi-row stacking - downstream packing".
