Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of flexible packing conveyor, in particular to a flexible packing conveyor based on multi-specification category switching. BACKGROUND

[0002] In the field of bottled water production, due to the difference in consumption scenarios (such as outdoor portability and home stockpiling), products often cover multiple specifications such as small bottles below 550 mL and large bottles above 1.5 L, and as the order fragmentation trend intensifies, the production line needs to frequently switch between different bottle type packing tasks. When facing multi-specification combination orders on e-commerce platforms, production needs to be split.

[0003] The current technical solutions in the field of flexible packing of bottled water generally have 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 often use single grippers or multiple grippers with synchronized actions for operation. Their movement patterns are fixed and cannot be alternately cycled. The grippers have a lot of invalid idle time, which not only leads to low efficiency of individual machines, but also slows down the overall production rhythm due to inconsistent action tempo. On the other hand, existing conveying mechanisms often use conveying belts running in the same direction to connect them. The material flow is single, and there is a lack of reverse or reverse layout chain plate conveyors to cooperate with them, making it difficult for bottled water to form an effective buffer and arrangement space between the material transfer and regulation links. This not only limits the flexible adjustment capability of the arrangement formation of bottled water of different specifications, but also affects the coordination of upstream and downstream equipment due to process interruption, making it difficult to balance efficiency, flexibility, and smooth operation as a whole.

[0004] Therefore, it is of urgent practical significance to develop a new packing system that can introduce an alternate gripping and placing mechanism to eliminate waiting gaps and use a reverse conveyor belt to achieve seamless process connection, in order to improve the overall efficiency of the production line and enhance the multi-specification adaptation capability.

[0009] Further, the conveying mechanism is composed of two chain plate conveying belts with opposite directions, and the chain plate conveying belts are driven by external driving devices to realize the arrangement of bottled water.

[0010] Further, the material transfer mechanism comprises two first electric lifting push rods fixed in the mounting grooves on the top of the first support frame, the top of the first support frame is movably connected with two first drive gears and two second drive gears through bearings, a polygonal limiting groove is formed in 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 connecting rod is connected to the top end of the corresponding first electric lifting push rod on 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.

[0011] Further, a through groove is formed through 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 with a mounting sleeve through the through groove, a first electric clamping jaw is fixedly installed in the mounting sleeve through bolts, and a servo motor for rotating the second drive gear is fixedly installed on the top of the inner wall of the first support frame.

At the same time, the system can accurately adapt to the single row number requirement of bottled water of different specifications by flexibly adjusting the number of clamping jaws and the number of alternating clamping, such as 2 bottles of large bottled water being formed by 2 times of alternating clamping, and 6 bottles of small bottled water being arranged in a row by 6 times of alternating clamping. The flexible design combined with the accurate control of the material receiving mechanism on the number of rows enables the system to quickly and regularly form a target formation (such as 2 rows of large bottles and 4 rows of small bottles) on the second conveyor, and finally realize seamless connection with the downstream packaging equipment. The whole process is closely connected, with less waiting time, which greatly improves the overall efficiency and adaptability of the packaging process while ensuring the accuracy of the arrangement.

Detailed Implementation

[0018] 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.

[0019] 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. 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. The top of the first rack 101 is provided with a positioning mechanism for assisting the delivery and guidance of 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 material transfer mechanism for transferring bottled water on the top of the first rack 101 to the conveying mechanism, and the inner side of the third support frame 203 is provided with a receiving mechanism for integrally transporting the bottled water arranged on the top of the conveying mechanism.

[0020] The inner side of the first rack 101 is provided with a first conveying belt 901, and the inner side of the second rack 102 is provided with a second conveying belt 902. Both the first conveying belt 901 and the second conveying belt 902 are powered by external driving devices to realize the delivery of bottled water.

[0021] A plurality of lifting push cylinders 3 are fixedly installed on both sides of the first rack 101, and the output end of each lifting push cylinder 3 is fixedly connected with a support plate. The positioning mechanism comprises a plurality of sleeves 401 fixed on the top of the support plate, a sliding frame 402 slidably connected in the sleeve 401, a horizontal electric push rod 403 fixedly installed on the outer side of one end of the sleeve 401 for driving the horizontal movement of the sliding frame 402, a plurality of positioning frames 404 fixedly connected to the side wall of the sliding frame 402, a plurality of screw holes formed in the side wall of the positioning frame 404, and a plurality of guide wheel sets 405 fixedly installed on the positioning frame 404 through the screw holes, wherein each guide wheel set 405 comprises a plurality of guide wheels.

[0022] Note: The number of guide wheel sets 405 needs to be adjusted flexibly according to the height of the bottled water. When the bottled water is high, the number of guide wheel sets 405 on the positioning frame 404 is increased to ensure more stable guidance and support for the bottle body. When the bottled water is low, the number of guide wheel sets 405 is reduced to avoid interference between the guide wheels and the bottom of the bottle body.

[0023] The conveying mechanism comprises two chain plate conveying belts 501 with opposite directions, and the chain plate conveying belts 501 are driven by external driving devices to realize the arrangement of bottled water.

[0024] The material transfer mechanism comprises two first electric lifting push rods 601 fixedly installed on the top of the first support frame 201, two first drive gears 602 and two second drive gears 603 movably connected to the top of the first support frame 201 through bearings, a plurality of polygonal limiting grooves formed at the center of the first drive gear 602, a plurality of adapter rods 604 slidably connected in the polygonal limiting grooves, the top end of each adapter rod 604 and the top end of the corresponding first electric lifting push rod 601 being jointly connected to the bottom of a same horizontal plate 605, the top end of each adapter rod 604 being rotatably connected to the bottom of the horizontal plate 605, and the top end of each first electric lifting push rod 601 being fixedly connected to the bottom of the horizontal plate 605.

[0025] A through groove is formed through 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 with the mounting sleeve 606 through the through groove, the first electric clamping jaw 607 is fixedly installed inside the mounting sleeve 606 through a bolt, and the inner wall top of the first support frame 201 is fixedly installed with a servo motor 608 for rotating the second drive gear 603; The first drive gear 602 and the second drive gear 603 are connected through the chain 609.

[0026] Embodiment two: as shown in Figure 1 , Figure 8 The material receiving mechanism includes a sliding seat 701, a plurality of supports are fixedly installed on the inner wall top of the third support frame 203, a sliding rod and an electric reciprocating lead screw 9 are arranged on the inner side of the support, the electric reciprocating lead screw 9 is rotationally connected with the support, the sliding rod is fixedly connected with the support, and the sliding seat 701 is matched with the electric reciprocating lead screw 9 and the sliding rod through the threaded grooves and the sliding grooves formed in the side wall thereof.

[0027] The bottom end of the sliding seat 701 is fixedly connected with a second electric lifting push rod 702, the inner wall top of the third support frame 203 is fixedly installed with a third electric lifting push rod 8, and the bottom end of the second electric lifting push rod 702 is fixedly connected with a bearing frame 703.

[0028] The bottom end of the third electric lifting push rod 8 is fixedly connected with a material blocking plate 10.

[0029] In combination with Embodiment one and Embodiment two, the working principle of the present application is as follows: Along the feeding direction of the flexible boxing conveyor, the end of the first rack 101 away from the first support frame 201 is precisely connected with the upstream single-channel bottled water conveying device, and receives the bottled water conveyed by the upstream; after being guided by the alignment mechanism, grabbed and transferred by the material transferring mechanism according to the "row-column" mode, and regularly arranged by the conveying mechanism, the end of the second rack 102 away from the second support frame 202 is closely connected with the downstream boxing equipment, the material receiving mechanism transfers the regularly arranged bottled water to the second conveying belt 902, and finally conveys the bottled water to the boxing equipment to complete boxing. The number and arrangement mode of the clamping jaws are adjusted throughout the process to adapt to bottled water of different specifications, and "one row of two bottles (large bottled water) in two columns, one row of six bottles (small bottled water) in four columns" are typical examples, which can be flexibly adjusted, and "six small bottles (transferred three times) and two large bottles (transferred once)".

[0030] When the bottled water guided moves to the position below the first support frame 201 along the first conveying belt 901, the material transferring mechanism is started, the transfer from the first conveying belt 901 to the conveying mechanism is completed, and the number of transfer times is adjusted to adapt to the single-row number requirement of large and small bottles: The servo motor 608 drives the second drive gear 603 to rotate, and the first drive gear 602 is driven to rotate synchronously through the chain 609; the polygonal limiting groove of the first drive gear 602 is in sliding fit with the connecting rod 604, which not only drives the connecting rod 604 to rotate (adjusts the horizontal position of the clamping jaw), but also allows the connecting rod 604 to be lifted along with the first electric lifting push rod 601 (connected through the horizontal plate 605) (adjusts the height of the clamping jaw). Finally, the first electric clamping jaw 607 at the bottom end of the connecting rod 604 installed on the sleeve 606 realizes the rotating movement of “descending, clamping, ascending, rotating, descending, and unclamping”; The left clamping jaw first places the first bottle of water to the preset position of the conveying mechanism, rotates back to the original position, and waits for the third bottle of water; the right clamping jaw then places the second bottle of water to the corresponding position of the conveying mechanism, rotates back to the original position, and waits for the fourth bottle of water. The above-mentioned “left clamping → right clamping → left placing → right placing” alternating rhythm is repeated to realize the continuous transfer of bottled water and avoid the waste of efficiency caused by the waiting of a single clamping jaw.

[0031] The two first electric clamping jaws 607 adapt to the “single row number” requirement of different specifications of bottled water through “alternating clamping times” and “placement position planning”: Large bottles of water (single row of 2 bottles): alternating clamping 2 times can complete a single row: the left jaw clamps the first large bottle of water and places it to the “single row left position” of the conveying mechanism; the right jaw clamps the second large bottle of water and places it to the “single row right position” of the conveying mechanism. After 2 times of alternating clamping, the queue of “one row of 2 bottles” is directly formed without additional adjustment.

[0032] Small bottles of water (single row of 6 bottles): 6 times of alternating clamping are required to complete a single row, and the placement position is planned in the order of “left → right → left → right → left → right”: the first time (left jaw): placed to “single row 1st position”; the second time (right jaw): placed to “2nd position”; the third time (left jaw): placed to “3rd position”; the fourth time (right jaw): placed to “4th position”; the fifth time (left jaw): placed to “5th position”; the sixth time (right jaw): placed to “6th position”; after 6 times of alternating, 6 small bottles of water are closely arranged along the horizontal direction on the conveying mechanism to form a complete queue of “one row of 6 bottles”.

[0033] The formation of the number of rows completely depends on the moving times of the sliding seat 701 of the receiving mechanism: each time the sliding seat 701 moves, one “single row” on the chain plate conveying belt 501 is transferred to the second conveying belt 902; several times of movement, several rows are stacked on the second conveying belt 902, and the specific action is as follows: Single grab and transfer of sliding seat 701 (single row): grab single row: the electric reciprocating wire rod 9 on the third support frame 203 drives the sliding seat 701 (slides along the slide rod) to move above the "grab position" of the chain plate conveyor 501; the second electric lifting push rod 702 drives the bearing frame 703 to descend, and the second electric clamping jaw 704 (2 groups of second electric clamping jaws 704 are used to grab 2 bottles of single row for large bottles, and 6 groups of second electric clamping jaws 704 are used to grab 6 bottles of single row for small bottles) adjusted according to the number of single row bottles are clamped; At the same time, the third electric lifting push rod 8 drives the material blocking plate 10 to descend, preventing the bottle from tilting, and the sliding seat 701 with the clamped "single row" moves above the second conveyor 902, the second electric lifting push rod 702 descends, the second electric clamping jaw 704 releases the clamp, and the single row is placed on the second conveyor 902; then the sliding seat 701 returns to its original position, ready for the next grab. The number of times the sliding seat 701 moves = the number of rows (core adaptation): large bottles require "2 rows": the sliding seat 701 repeats the above "grabbing → transferring → returning" action twice - the first single row is transferred to the second conveyor 902 the first time, and the second single row is transferred to the second conveyor 902 the second time (arranged side by side / with spacing with the first row), and finally the second conveyor 902 forms a "2 rows, 2 bottles per row" formation.

[0034] Small bottles require "4 rows": the sliding seat 701 repeats the above action 4 times - each time transferring a "single row of 6 bottles" to the second conveyor 902, and after 4 times, a "4 rows, 6 bottles per row" formation is formed. (Note: The second conveyor 902 remains stationary during the transfer of the sliding seat 701 to ensure that each row can be smoothly stacked in the pre-set position without deviation.) After the target number of rows (2 rows for large bottles and 4 rows for small bottles) is stacked, the second conveyor 902 (driven by the outside) transports the complete "multi-row bottled water" away from the end of the second rack 102 away from the second support frame 202; Since this end is closely connected to the downstream boxing equipment, the multi-row bottled water directly enters the boxing equipment, completing the complete closed loop of "upstream feeding-alternating transfer-multi-row rowing-downstream boxing".
